Is there a nXhtml untag element function?

[andylech]

I recently switched back to GNU Emacs after I found out about EmacsW32
and nXhtml.

I like both a lot but one of the things that drives me crazy about
nXhtml is that there doesn't seem to be anything like sgml-untag-
element from PSGML.  All it does is remove the start and end tags
around the current element, but I would think it has to be one of the
most important functions in any HTML/XHTML editing package.  I've
looked all over and I can't find anything like it.

Has anybody else found a solution to this problem?
