[xsl] Escaping nodeset content

---

---

I have an application where I need to convert, with an xsl 
transform, some nodeset to escaped text (i.e., <abc/> => 
"&lt;abc/&gt;").  Attached you will find some tests cases 
with a transform that kind-of does what I want, but it is not 
escaping the result.  Is there anyway to do what I want 
within an xsl transform?

I know this is a brain-dead way of processing XML, but the 
guy that designed the message I'm trying to generate didn't 
know much about including XML within another XML document 
(using namespaces and such) so he just put it in as text :(.  
We are planning on redesigning this at the end of this year 
but for now, we have to work within this design.

Thanks for any help.
