DESCRIPTION
        openjade is an implementation of the ISO/IEC 10179:1996 standard DSSSL
       language.  The  DSSSL  engine receives as input an SGML or XML document
       and transforms it into formats like:

       * XML representation of the flow object tree.

       * RTF format that can be rendered and  printed  with  Microsoft's  free
       Word Viewer 97

       * TeX format

       * MIF format that can be rendered and printed with Framemaker

       *  SGML  or  XML  format. This is used in conjunction with non-standard
       flow object classes to generate SGML, thus allowing openjade to be used
       for SGML/XML transformations.

       The  system  identifier of the document to be processed is specified as
       an argument to openjade. If this is omitted,  standard  input  will  be
       read.

       openjade  determines  the system identifier for the DSSSL specification
       as follows:

       1. If the -d option is specified, it will use the argument as the  sys-
       tem identifier.

       2. Otherwise, it will look for processing instructions in the prolog of
       the document. Two kinds of processing instruction are recognized:

       <?stylesheet href="sysid" type="text/dsssl">

       The system data of the processing instruction is parsed  like  an  SGML
       start-tag.  It will be parsed using the reference concrete syntax what-
       ever the actual concrete syntax of the document. The name  that  starts
       the  processing instruction can be either stylesheet, xml-stylesheet or
       xml:stylesheet. The processing instruction will be ignored  unless  the
       value  of the type attribute is one of text/dsssl, text/x-dsssl, appli-
       cation/dsssl, or application/x-dsssl. The value of  href  attribute  is
       the system identifier of the DSSSL specification.

       <?dsssl sysid>

       The system identifier is the portion of the system data of the process-
       ing instruction following the initial name and any whitespace.

       Although the processing instruction is only recognized in  the  prolog,
       it  need  not occur in the document entity. For example, it could occur
       The DSSSL specification must be an  SGML  document  conforming  to  the
       DSSSL architecture. For an example, see dsssl/demo.dsl.

       openjade supports the following options in addition to the normal Open-
       SP (see onsgmls(1)) options (note that all options are  case-sensitive,
       ie -g and -G are different options):

       -d dsssl_spec
              This  specifies  that dsssl_spec is the system identifier of the
              DSSSL specification to be used.

       -G     Debug mode. When an error occurs in the evaluation of an expres-
              sion,  openjade  will display a stack trace. Note that this dis-
              ables tail-call optimization.

       -c filename
              The filename arguments specify catalog  files  rather  than  the
              document  entity.  The document entity is specified by the first
              DOCUMENT entry in the catalog files.

       -s     Strict compliance mode. Currently the only effect is  that  jade
              doesn't  use  any  predefined character names, sdata-entity map-
              pings or name-characters. This is useful for checking that  your
              stylesheet  is  portable to other DSSSL implementations and that
              it is strictly compliant to the DSSSL specifications.

       -t output_type
              output_type specifies the type of output as follows:

              fot  An XML representation of the flow object tree

              rtf rtf-95  RTF (used for SGML/XML to RTF  transformations)  Mi-
              crosoft's Rich Text Format. rtf-95 produces output optimized for
              Word 95 rather than Word 97.

              tex TeX (used for SGML/XML to TeX transformations)

              sgml sgml-raw SGML (used for SGML/XML to SGML  transformations).
              sgml-raw doesn't emit linebreaks in tags.

              xml  xml-raw  XML  (used  for  SGML/XML to XML transformations).
              xml-raw doesn't emit linebreaks in tags.

              html  HTML (used for SGML/XML to HTML transformations)

              mif MIF (used for SGML/XML to MIF transformations)

       -o output_file
              Write output to output_file instead of the default. The  default
              filename  is  the name of the last input file with its extension
              replaced by the name of the type of output. If there is no input
              filename, then the extension is added onto jade-out.

       -V variable
              able  in  a style-sheet. Note that you will probably have to use
              some escaping mechanism for the spaces to get the entire  scheme
              expression parsed as one cmdline argument.

       -wtype Control  warnings  and  errors. Multiple -w options are allowed.
              The following values of type enable warnings:

              xml Warn about constructs that are not allowed by XML.

              mixed Warn about mixed content models that do not allow  #pcdata
              anywhere.

              sgmldecl  Warn  about  various dubious constructions in the SGML
              declaration.

              should Warn about various recommendations made in ISO 8879  that
              the  document  does  not  comply  with. (Recommendations are ex-
              pressed with ``should'', as distinct from requirements which are
              usually expressed with ``shall''.)

              default Warn about defaulted references.

              duplicate Warn about duplicate entity declarations.

              undefined  Warn  about  undefined elements: elements used in the
              DTD but not defined.

              unclosed Warn about unclosed start and end-tags.

              empty Warn about empty start and end-tags.

              net Warn about net-enabling start-tags and null end-tags.

              min-tag Warn about minimized start and end-tags.  Equivalent  to
              combination of unclosed, empty and net warnings.

              unused-map Warn about unused short reference maps: maps that are
              declared with a short reference mapping  declaration  but  never
              used in a short reference use declaration in the DTD.

              unused-param  Warn about parameter entities that are defined but
              not used in a DTD. Unused internal parameter entities whose text
              is INCLUDE or IGNORE won't get the warning.

              notation-sysid  Warn about notations for which no system identi-
              fier could be generated.

              all Warn about conditions that should usually be avoided (in the
              opinion  of  the author). Equivalent to: mixed, should, default,
              undefined, sgmldecl, unused-map,  unused-param,  empty  and  un-
              closed.

              A  warning  can be disabled by using its name prefixed with no-.
              Thus -wall -wno-duplicate will enable all warnings except  those

              no-valid Do not require the document to be type-valid. This  has
              the  effect of changing the SGML declaration to specify VALIDITY
              NOASSERT and IMPLYDEF ATTLIST YES  ELEMENT  YES.  An  option  of
              -wvalid has the effect of changing the SGML declaration to spec-
              ify VALIDITY TYPE and IMPLYDEF ATTLIST NO ELEMENT NO. If neither
              -wvalid  nor -wno-valid are specified, then the VALIDITY and IM-
              PLYDEF specified in the SGML declaration will be used.

ENVIRONMENT
       OpenJade ignores the SP_CHARSET_FIXED and SP_SYSTEM_CHARSET environment
       variables  and always uses Unicode as its internal character set, as if
       SP_CHARSET_FIXED was 1 and SP_SYSTEM_CHARSET was unset. Thus  only  the
       SP_ENCODING  environment variable is relevant to OpenJade's handling of
       character sets.

OPENJADE EXTENSIONS
       The following external procedures are available. These external  proce-
       dures are defined by a prototype in the same manner as in the standard.
       To use one of these external procedures, you must make use of the stan-
       dard external-procedure procedure, using a public identifier of "UNREG-
       ISTERED::James Clark//Procedure::name" where name  is  the  name  given
       here, typically by including the following in the DSSSL specification:

       (define  name  (external-procedure  "UNREGISTERED::James  Clark//Proce-
       dure::name"))

       Note that external-procedure returns #f if it doesn't  know  about  the
       specified  public  identifier.  You  can  use this to enable your DSSSL
       specifications to work gracefully with other implementations  which  do
       not support these extensions.

       For  external procedures added by the OpenJade team, use a public iden-
       tifier of the form "UNREGISTERED::OpenJade//Procedure::name".

       An easy way to get access to all external  procedures  is  to  use  the
       style specification dsssl/extensions.dsl#procedures. The file dsssl/ex-
       tensions.dsl also contains style specifications which make the nonstan-
       dard flow object classes and inherited characteristics supported by the
       backends available in a convenient way.

       Debugging

       (debug obj)

       Generates a message including the value of obj and then returns obj.

       Simple-page-sequence header/footer control

       (if-first-page sosofo1 sosofo2)

       This can be used only in the specification of the value of one  of  the
       header/footer  characteristics  of  simple-page-sequence.  It returns a
       sosofo that will display as sosofo1 if the page is the  first  page  of
       (all-element-number)

       (all-element-number osnl)

       This  is  the same as element-number except it counts elements with any
       generic identifier. If osnl is not an element returns #f, otherwise re-
       turns 1 plus the number of elements that started before osnl. This pro-
       vides an efficient way of creating a unique identifier for any  element
       in a document.

       External entity access

       (read-entity string)

       This  returns  a  string containing the contents of the external entity
       with system identifier string. This should be used only for textual en-
       tities (CDATA and SDATA), and not for binary entities (NDATA).

       POSIX locale access

       (language lang country)

       This  procedure  returns an object of type language, if the system sup-
       ports the specified language. lang is a string or symbol giving the two
       letter language code. country is a string or symbol giving the two let-
       ter country code.

       This procedure uses POSIX locales. It is an OpenJade  addition.  It  is
       not supported on all operating systems.

       Extended standard procedures

       (sgml-parse sysid #!key active: parent: architecture:)

       This  allows  you to specify an SGML architecture with respect to which
       the document should be parsed. It is an OpenJade addition.

       (expt q k)

       This allows you to raise a quantity to an  integral  power.  It  is  an
       OpenJade addition.

LIMITATIONS
       This  section  describes  the  limitations of the front-end (the gener-
       al-purpose DSSSL engine); each backend also has its own limitations.

       openjade doesn't allow internal definitions at the beginning of  bodies
       and the (test => recipient) variant of cond clauses.

       openjade  supports  only a single, fixed grove plan which comprises the
       following modules:

       * baseabs

       It doesn't implement the following parts of SDQL: HyTime support,  aux-
       iliary parsing, node regular expressions.

       Query  rules,  sosofo synchronization, indirect sosofos, reference val-
       ues, decoration areas and font properties are not supported.

       Note that only inherited characteristics that are  applicable  to  some
       supported flow object can be specified.

       Character/glyph handling

       It only supports a single pre-defined character repertoire. A character
       name of the form U-XXXX where XXXX are four upper-case hexadecimal dig-
       its,  is  recognized  as  referring  to the Unicode character with that
       code. For many characters, it is also possible to use the ISO/IEC 10646
       name in lower-case with words separated by hyphens.

       Some  common SDATA entity names from the ISO entity sets are recognized
       and mapped to characters. In addition an SDATA entity name of the  form
       U-XXXX, where XXXX are four upper-case hexadecimal digits, is mapped to
       the Unicode character with that code.

       OpenJade   now   supports   the    standard-chars,    map-sdata-entity,
       add-name-chars, add-separator-chars and char-repertoire declaration el-
       ement forms, allowing a  style-sheet  to  define  additional  character
       names,  sdata entity mappings, name characters (i.e. characters allowed
       in identifiers) and separator characters. Currently the only recognized
       character  repertoire  is  the  built-in  repertoire. It has the public
       identifier "UNREGISTERED::OpenJade//Character Repertoire::OpenJade".

       Validation

       Several things that it  would  be  desirable  to  have  checked  aren't
       checked:

       *  When  the  allowed value of an inherited characteristic is a symbol,
       OpenJade checks only that the value is a symbol that is allowed as  the
       value  of  some characteristic; #t and #f are treated as a special kind
       of symbol in this case.

       * OpenJade doesn't check whether a flow object is occurring in  a  con-
       text where it is allowed.

       *  OpenJade does not prevent flow objects being attached to the princi-
       pal port of a flow object when the flow object shouldn't have a princi-
       pal port.

       * Most type-checking is done at run-time not compile-time.

       *  OpenJade  does  not check for non-inherited characteristics that are
       required to be specified.

       * It doesn't check that optional features that have been used were  de-
       clared in the features form.

       openjade -t rtf file.sgml

       Using a different stylesheet:

       openjade -t rtf -d docbook.dsl file.sgml

       Using the print style specification contained within the stylesheet

       openjade -t rtf -d docbook.dsl#print file.sgml

       And use the html specification within the style  sheet  to  convert  to
       html

       openjade -t sgml -i html -d docbook.dsl#html file.sgml
