Re: [xml-dev] Including XHTML into another DTD?

[Dan Vint <dvint@dvint.com>]

Even this is more complicated than what I'm trying to determine. All 
these enties are about including or not and changing the prefixes or 
not. I was hoping to find the 2 or 3 lines that just include the 
MathML in HTML and hopefully show how it controls where it can be 
used. That is not allowing MathML to be used everywhere in an html document.
