F.2.1 New in this release

• The down-conversion is now driven by a script, sgml2docs, as described in Section 6.2. This required a non-trivial amount of internal rearrangement, none of which should be visible to authors.
• Significantly upgraded the error handling in the case where a docxref cross-reference target cannot be resolved. The stylesheet does not complain in this case, but instead synthesises a reference to the RAL document server, as long as the public identifier is in the correct format. Jade still gives a warning in this case (which it's not easy to turn off), but it doesn't invalidate the document.
• The SGML declaration was changed in such a way that IDs within the document are now case-sensitive. This could not be done without making all the other SGML in the application case-sensitive as well. This required substantial reorganisation. As well as forcing the whole system to be a little tighter (no bad thing), this helps pave the way for an eventual XML version of the DTD (XML has a fixed declaration which makes documents case-sensitive).
• The paragraph-content parts of the General DTD was split off into a separate DTD fragment, paracontent-0.6.dtd, and the programcode DTD was modified to incorporate that, so that all of this structure is now available within the programcode DTD.
• The paracontent and General DTDs were made fully compatible with XML, by use of suitably cunning parameter entities (MOO, MXX, etc, and Full.SGML.Only) in the DTD.
• The LaTeX down-converter now supports the most important of the Oasis Table attributes. The HTML down-converter should follow soon.
• The dtddescription DTD and associated utilities (in doc/dtd2sgml) have been converted to XML, and a system for including comments on the DTD has been implemented. This isn't quite live yet, but should be available immediately after this release, to support discussion on the release 0.7 DTDs.
