Re: [xml-dev] SGML DTDs for HTML 5.1

Yes, I think you're right and I should leave the entities alone.
Thanks for the link.

My motivation for removing some entities for the permissive DTD is
that the SGML declaration (WebSGML/ISO 8879 Annex K) only allows a
single code point to be specified as the replacement for an entity,
while HTML's entities also contain some multi-code point sequence
(as detailed in
http://sgmljs.net/docs/html5.html#html5-named-character-references).
And I really want to align with WebSGML here, as for my application,
having to retrieve entity sets over the net kills it performance-wise.
Thus I was thinking that since most of the entities come from MathML,
and MathML doesn't really belong in a group next to HTML and SVG
anyway from a browser implementation PoV anyway, I could conveniently
drop some entities.

Also, using entity sets isn't quite the same as using predefined
entities, because predefined entiies, as a definitorial concept,
capture that the browser, rather than some preprocessing system
handles expansion into code points.
