Yeah, but at that point it isn't XHTML anymore. There is a difference 
between properly formed XHTML and what this generator dumps out. The 
generator is following the rules of XML, which are not the rules of 
XHTML. So the problem isn't with XHTML, the problem is with the 
generator creating things that aren't really XHTML. solprovider's 
generator may be what's needed.

My serializer creates good HTML if the source is already HTML-like
e.g. XHTML. Rereading the original post suggests the serializer may
not solve the original issue.

Rainer wants to allow editors to enter a TEXTAREA within the TEXTAREA
used for entering RichText.  TEXTAREAs cannot be nested.  When the
document is opened again for editing, the nested TEXTAREA closes the
editor field and destroys the rest of the field.  Rainer needs to
replace the nested TEXTAREA tags with something else before sending to
the browser, then use JavaScript to translate the nested tags.  From
the explanation, the nested TEXTAREA saves correctly so:
Saved field contains ... <TEXTAREA ... ></TEXTAREA> ...
Send to browser as ... [TEXTAREA ... ][/TEXTAREA] ...
After loading, browser translates to ... <TEXTAREA></TEXTAREA> ...

While this is probably possible, the document editors were not
designed to be form creators.  Nested FORMs are likely to be the next
issue.  Why show a TEXTAREA without a FORM element?  The FORM element
must be processed like the TEXTAREA so the nested FORM does not
destroy the document editor.
