- This file describes recent user-visible changes in sgmls. Bug fixes
- are not described. See the man pages for more details.
-
- Version 1.2
- ===========
-
- You can use catalog entry files in the format defined in the SGML Open
- Draft Technical Resolution on Entity Management to map public
- identifiers and entity names onto system identifiers.
-
- Version 1.1
- ===========
-
- The rast filter converts the output of sgmls to RAST format. See
- rast.man.
-
- There have been some changes to the output format: system and public
- identifiers for external entities and notations are specified using
- the new `s' and `p' commands; the filenames for external entities are
- specified using the new `f' command rather than being arguments to the
- `E' and `S' commands; the `\s' escape sequence is no longer generated;
- an `S' command is generated for an entity mentioned in a `{' command;
- RS characters are no longer stripped and are represented by `\012'.
-
- The -c option now takes an argument giving the name of the file to
- which the report of capacity calculations should be written. The
- report is in RACT format.
-
- sgmls can now handle non-seekable devices (such as pipes). If no
- filenames are specified on the command line, sgmls will read the
- document entity from standard input. A filename of `-' can also be
- used to refer to standard input.
-
- The output format no longer distinguishes attributes whose declared
- value is ID, IDREF or IDREFS and uses the TOKEN keyword for these.
- (The ESIS does not distinguish these attributes.)
-
- The -a option is no longer allowed.
-
- Version 1.0
- ===========
-
- Eight bit characters can be made name characters.
-
- Ambiguous content models are always detected. The -a option is ignored.
-
- Version 0.8
- ===========
-
- On Unix systems, the configure script can automatically generate
- config.h from unix.cfg.
-
- An APPINFO parameter in the SGML declaration other than NONE is output
- as a `#' command.
-
- sgmls has a -iNAME option which defines a parameter entity NAME with
- replacement text "INCLUDE".
-
- sgmls has a -u option that warns about undefined elements.
-
- In SGML_PATH, the public text designating sequence (escape sequence)
- is now accessed with %E rather than %S. %S now gives the system
- identifier. When a system identifier is supplied, SGML_PATH will be
- used to generate a filename only if SGML_PATH uses %S and the system
- identifier does not contain (semi-)colons.
-
- An accordance with Amendment 1 to ISO 8879:1986, in the SGML
- declaration `ISO 8879:1986' rather than `ISO 8879-1986' is required.
-
- With MS-DOS, errors can be redirected to a file using the -f option.
-
- Version 0.7
- ===========
-
- More quantity limits can be changed. In particular, GRPCNT, GRPLVL
- and GRPGTCNT can be increased up to 253; NAMELEN can be increased to
- 239. Names are now dynamically allocated (that is, the amount of
- memory used to store a name depends on the actual length of the name
- rather than on value specified for NAMELEN.)
-
- sgmlasp supports a -n option which disables upper-case substitution
- for names in replacement files.
-
- sgmls has a -p option which makes it parse only the prolog.
-
- The format of the I command has been changed: CDATA and SDATA entities
- are distinguished using a keyword rather than by surrounding SDATA
- entities with \|s.
-
- Version 0.6
- ===========
-
- A concrete syntax can now be specified explicitly in the SGML
- declaration, and various parts of the reference concrete syntax can be
- changed, including some quantity limits.
-
- The treatment of notation identifiers and the syntax of the N output
- command have been changed.
-
- SUBDOC support works with MS-DOS.
-
- The -n option has been removed; references to subdocument entities are
- always resolved.
-
- It is no longer possible to change the implied SGML declaration using
- environment variables. You must use an explicit SGML declaration
- instead.
-
- The V output command has been removed.
-
- sgmlsasp supports multiple replacement files.
