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.


I have tried adding a "cdata-section-elements" section
to the xsl:ouput tag telling it to treat
Text.Description & Text.LongDescription as CDATA.
This creates the following output

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.
