Let me re-phrase this. Are there examples of mixed-model
use-cases, where one DTD does not have mixed-content,
and a subordinate/contained DTD (ANY) does use mixed-content.
For example, often times people put HTML inside eCommerce
"description" fields, texts which are otherwise free of
mixed content. (Hence the modular XHTML effort)
Anyway, I feel stupid for not phrasing the question
correctly... I even did some SGML publishing work
3 years back using Omnimark. So sorry.

Well, the proposal is, in-essence, what the DOM model
of XML does for all content -- however, given that XHTML
will most likely be machine generated anyway; this
little tweak would allow a non-mixed content API to
be useable for eCommerce work. Moving XHTML into
the "special case" category.
So, I guess I was really trying to ask:
1. How common is mixed model XML usage, where
a mixed-content DTD is used as a subordinate
document to a non-mixed-content model.
2. Would it make sense to allow include
<xhtml:plain> as a no-op for cases where
xhtml mixed-content is included in eCommerce
So. I was wondering if XHTML should be
This is in-essence what the DOM model does for all content, and it makes
hard for strict non-mixed use cases.
So, I was wondering if XHTML should
not assume mixed-content
