DocBook V4.3: SGML tweaks and Emacs/psgml

[Karl Eichwalder <ke@gnu.franken.de>]

Without the patches 1/ and 2/ onsgmls will not parse an SGML using the
supplied SGML declaration (docbook.dcl).

1/
Error message:

echo '<!DOCTYPE book SYSTEM "docbook.dtd">

' | onsgmls -E 1 -s docbook.dcl -
onsgmls:dbpoolx.mod:815:17:E: character ":" invalid: only "CDATA", "ENTITIES", "ENTITY", "ID", "IDREF", "IDREFS", "NAME", "NAMES", "NMTOKEN", "NMTOKENS", "NOTATION", "NUMBER", "NUMBERS", "NUTOKEN", "NUTOKENS" and parameter separators allowed
onsgmls:I: maximum number of errors (1) reached; change with -E option

Because of the colon in "xml:base" I propose to change the SGML
declaration as follows:

The "tbl.frame.attval" entity definition in htmltblx.mod wins and thus
the attribute values "none" and "all" will appear twice.  This is not
allowed.  I propose to define "tbl.frame.attval" in a way following
HTML 4.01:

Not a DTD issue, but maybe helpful: To make Emacs/psgml aware of this
change add to .emacs:

(eval-after-load "psgml-parse"
	'(modify-syntax-entry ?_ "_" sgml-parser-syntax))
(eval-after-load "psgml-parse"
	'(modify-syntax-entry ?: "_" sgml-parser-syntax))
