Revision 1.11 - (hide annotations) (download)
Sat Apr 30 03:17:56 1994 UTC (32 years, 3 months ago) by connolly
Branch: MAIN
Changes since 1.10: +32 -13 lines 
Makefile:
* doctype-mosaic.sgml is obsolete: The "default" version of
the DTD parses everything now... (after a few tweaks here and there)

html.dtd:
* Changed BODY to allow %htext, making <P> start tags not necessary,
but keeping <P> as a container. This means I don't really need
a separate mosaid mode any more.

* Moved several of the features that are incompatible with extant
docs under a %HTML.Prescriptive feature set.

* Added HTML.Version entity, for use by code generation tools.
This entity varies according to the feature set used.

* Changed the "default" mode of some features:
+<!ENTITY % HTML.anchorNameCDATA "INCLUDE"
+<!ENTITY % HTML.PLAINTEXT "INCLUDE"
+<!ENTITY % HTML.font-phrase "INCLUDE"

* Changed several attribute names to coincide with their
values, for a hacked version of attribute minimization
support in libwww.

* Added %block to ADDRESS content


* Added a #DEFAULT entity so that undefined entities are legal
(Hmmm...)
