Hi Paul,

Yes its a problem.

Part of the issue is that some folks do not reliably distinuish
between an attribute of type anyURI, which there can be lots of per
element, and a link (which can have only one such attribute that forms
the link URI, if there is to be any metadata also associated with
that link  using standard and readily recognisable attribute names).
