Recipients only need to change if they lent @rel a
syntax/meaning/whateveryouwannacallit beyond the spec. If you assumed
@rel in HTML or XHTML was a URI, you went beyond the spec.

RDFa specifically ensured that existing *specified* interpretations of
@rel were preserved, i.e. link types. And RDFa specifically ensured that
the list of link types could be extended in the future without
interfering with our use of @rel including prefixed values which,
according to the spec, you should have simply ignored as local values.

I think that's what Steven means when he says we added a way to
interpret the @rel syntax without actually changing it, because there
*no* syntax specified other than CDATA.
