Tags and other artifacts of serialization are nonexistent in the XPath/XSLT
data model, since XML parsers are designed to sift through all that and
tell applications such as XSLT processors only about the important logical
constructs (elements, attributes, character data, and their relationships
to one another).

So what you are asking for is a way to serialize this parsed data (nodes in
the source or result tree) during processing, putting the serialized markup
and text into a text node child of the description element. This is painful to
do in XSLT but not impossible. Have a look at

 http://www.xmlportfolio.com/xml-to-string/

In your stylesheet you just need to call the xml-to-string template, passing
the node-set parameter that contains the top of the XHTML nodes you want to
serialize.
