README.html: Removed references to doctype-mosaic. Changed public identifier to reference no particular version of the DTD (sneaky...) Added links to a few interesting things. html.decl: removed "255 1 UNUSED" stuff, as per somebody's suggestion... WEK or somebody... can't exactly remember. Added comment about RE vs SEPCHAR stuff... html.dtd: * Added comments in the HTML.Prescriptive marked section moved bogus second public identifier to another file... * Removed bogus isindexatend, HTML.GO, HTML.aEndOmissable stuff * added bodyBlockOnly feature test * changed KEY, U to feature-test-controlled elements * added a @@ note about relative HREF's * changed BASE HREF attr to be required * changed amp, lt, etc. entities to be CDATA entities, so they don't get parsed at runtime. * moved obsolete elements after forms optional.html: updated w.r.t KEY, U ---------------------------- revision 1.11 date: 1994/04/30 03:17:56; author: connolly; state: Exp; lines: +32 -13 Makefile: * doctype-mosaic.sgml is obsolete: The "default" version of the DTD parses everything now...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

start tags not necessary, but keeping

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: + -- The GO element used in ORA GNN. What is this??? --> > > -- infer tags, as in ORA GNN stuff --> > > -- allow ISINDEX after HEAD and BODY, as in ORA GNN stuff --> NEXTID is "on" by default -- it doesn't hurt anything, I guess. ISINDEX is allowed in %body-content if HTML.forms is "on" @@ Hmmm... this means one must search the whole doc, not just the head, to see if it's an index. Bad. Expanded the BLOCKQUOTE content model to include all sorts of %block stuff -- not just P and ADDRESS. Fixed missing * in FORM content model. ---------------------------- revision 1.8 date: 1994/04/09 01:02:10; author: connolly; state: Exp; lines: +275 -128 * Added feature test entities for stuff that's handled different ways by different HTML implementations or specifications. * Removed %headelement, %bodyelement, %oldstyle, in favor of using OMITTAG to infer , tags. * Changed %URL to %URI, and cited specification * Revamped %linkattributes in light of feature test entities * Revamped HTML, HEAD, elements in light of feature test entities * Anchor names may or may not be ID's based on the HTML.anchorNameID feature-test entity. * Changed %inline to be composed of %phrase and %font, where %font is controlled by %HTML.font-phrase * Changed EM, CODE, SAMP, etc. from (#PCDATA) to (%htext)+ * Added P, BR to %text * replaced %stext with %block and %htext * Changed BODY, A content models. * Added BR element * Changed DL content model to (DT*, DD?)+, changed DT, DD from EMPTY to containers with omissable end tags.

Changed BODY, DL, etc. to have ELEMENT content. Changed lists to allow embeded lists. Removed NEXTID element -- should be a processing instruction.

The PRE style newline handling should be a different NOTATION. Changed content model of %inline elements to inlcude A. Changed content model of A to ANY. B, I, U, TT only allowed inside PRE. EM, STRONG, etc. not allowed inside PRE.
