No ... CDATA boundaries are not preserved in the XPath data 
model.  CDATA sections are just syntactic sugar and as such are not 
distinguished in the XML Information Set (see Appendix D):

Just by using the identity transform you will get the identical 
*information* in the result tree as in the source, you just won't get 
the identical syntax for that information.

A downstream application based on the XML information set will not 
see a difference if the characters of your CDATA section are instead 
individually escaped.

I hope this helps.
