Well this one would not work. HTML is based on SGML which cannot always 
directly included in XML.

You will either have to include it escaping the special characters:

<content:part type="text/html">
    &lt;html xmlns=".......">.....&lt;/html>
</content:part>

Or you have to restrict it to use XHTML (which is based on XML as you know):

<content:part type="application/xhtml+xml">
     <html xmlns="......">.....</html>
</content:part>

... and you would have to define (either implicit or explicit) which 
types are included directly and which have to be escaped.

Personally I prefere using XHTML instead of HTML. But if you are really 
XHTML (1.1) aware, you should also have no problems, that XHTML-IM has 
its own profile of XHTML.

Due to my feelings it is correct, that we limit the set of allowed 
elements. If a client has problems implementing this, it is caused 
because they are trying to use a UI widget, that is designed for HTML 
and not for XHTML.

But I am no client developper, so please let the other people discuss 
this topic ...
