But this still doesn't let you define the source of the RDDL link
independently of XHTML links like that was possible in RDDL 1.0.

The real good thing about RDDL 1.0 is that <rddl:resource/> are
fragments that can have a meaning by themselves: they can embed a piece
of rich documentation about the resource that they describe and they can
be very useful for creating modular vocabularies.
