This seems really questionable.  Using CDATA sections to embed
other XML that's known not to contain any seems just fine.
On the other hand, relying on that CDATA section to tell you
where it is smells bad.  Wouldn't it have been immensely
better to do

<mydoc>...
  <included-doc><![CDATA[ <something-else /> .. 
  ]]></included-doc> ...
</mydoc>

Then the CDATA does what it's supposed to, simplify
escaping, and the tags do what they're supposed to,
provide semantic markup saying what pieces of text
really are.  -Tim
