Rails - Dec 2010 - [OT] Embed xml doc within an xml doc from untruted source?

Off topic but I am sure someone here might have seen this:
I have a web service which returns an xml document. Within this document I
embed an xml document from a foreign source (so I dont want the validity of
my xml to be predicated on whatever this provider happens to return. This
foreign xml doc by the way contains a CDATA within it, so wrapping the full
xml doc in CDATA does not work. The best I can come up with is to escape the
entire foreign xml with <lt; and <gt;. Is there another better way to go
about this?

I''ve seen the suggestion to just escape the ]]> in the inner CDATA
to
]]&gt;

But this seems like a dreadful way to go about the problem.  If you can 
reanalyze your design so you don''t need the nested XML documents, do; 
otherwise, take this discussion to an XML community where it will be on 
topic and where more XML gurus will be able to answer your question.
