A similar example is that of Web annotations, commentaries, 'weblogs' etc.
Mostly these are pretty simple to handle in RDF, but a few applications
(eg. see http://www.memepool.com, http://www.slashdot.org/) make good use
of embedded hyperlinks wthin the commentary text. More generally,
'document like' content as against 'data like' content. While the XML
markup could in principle be unfolded into a little web of RDF Seq
structures (to preserve ordering), or a linked list or similar, I expect
many apps will just treat the markup as datatyped content to be passed on
to XML/HTML  oriented components. Which raises question of what the URI
would be for such a datatype, and whether we look to the XML Structures or
XML data types spec for this...
