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... Dan
