This is an indication that the XML processor in your XSLT processor is not 
communicating the correct information to the XPath data model builder ... 
it is making a text node out of the CDATA markup and it should not be doing so.

Right ... because on the way in it read your CDATA markup as text, not as 
markup.

Your files work just fine with Instant Saxon 6.5.3 (copied below).

I hope this helps.
