Hi David,
I'm writing you because your are maintainer of
http://www.w3.org/2003/entities/
As more and more markup languages are not defined in the terms of DTD,
but they use modern schema languages like RELAX NG or W3C XML Schema,
there is known problem with entity definitions. Such entities are
usually defined as a part of DTD and if you are using DTD everything is
OK. However if you don't want rely on DTD you can just include entity
definitions alone, like:
<!DOCTYPE article [
<!ENTITY % isoamsb PUBLIC
"ISO 8879:1986//ENTITIES Added Math Symbols: Binary
Operators//EN//XML"
"http://www.w3.org/2003/entities/iso8879/isoamsb.ent"
>
%isoamsb;
]>
Problem is that if you want to include more entity files then one, your
internal set will get quite large.
Do you think that it will be possible to create "master" entity
definition file as part of XML Entity Declarations project? This file
should include all other entity definitions files (or there can be
separate "master" file for each set like XHTML, MathML, ...) so
referencing this file from your internal subset will make all entites
available to document author.
The need for such "master" entity file came from discussion about
DocBook V5.0 combined with MathML.
If you think that it will be possible to extend current entity
definition with this new feature I will be happy to provide your further
input and assistance.
TIA,
Jirka
