Whether we need a new property seems to depend on whether a fragment
of a webpage could legitimately be described as a foaf:Document. The
definition of that class is pretty broad, so I think its open for
debate. If that is the case, then you could probably just get away

x foaf:page <http://www.example.org/document.html#section>.

If not, then this might be useful:

The range of such a property would be left open. You could imagine various ways to address a section: using fragment identifiers (element IDs in a HTML document, XPointer) or using [1].
