Inheriting XHTML dtd into "my.dtd"

Hello,

I'm wondering if there's an elegant way to inherit the XHTML dtd w/in a custom dtd. Bascially, what I'd like to do is to be able to use xhtml tags w/in my xml docs w/o having to explictity declare each tag. Has anyone done this? Can you throw some useful links my way and maybe even an example?

Thanks.

I'd look into Modular XHTML at www.w3.org

They've created XHTML+MathML+SVG profiles using it, I don't see why you couldn't do the same.

Thx for the reply jkd.

I've read through the WC3's modular implentation of xhtml dtds and I'm still a bit in the dark. What I want to do is allow my defined para element to accept elements from the xhtml text dtd & the xhtml hypertext dtd. Cam you recommend any faqs or docs on the web that discuss this type of implentation explicity?

Thank you Again.

I've figured this out....this was terriably simple...no need to use the xhtml mods....simply use the xhtml-basic.dtd:

http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd

Here's an example:

I'ved included the xhtml 'p' element as elelments of my defined 'para' element:

<!-- define para -->
<!ELEMENT para (p)*>
<!ELEMENT xhtml-text (p)*>

<!-- pull in w3c xhtml dtd-->
<!ENTITY % xhtml.mod
SYSTEM "xhtml.mod" >
%xhtml.mod;


and in the xhtml.mod file I've placed:

<!ENTITY % xhtml-basic.dtd PUBLIC "-//W3C//DTD XHTML Basic 1.0//EN" "http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd" >
%xhtml-basic.dtd;


Now the 'p' element and it's subelements are avaibable for use in my para element.
