Restricted inverse relations

Hi,

DAML supports only expressing inverse relation at the
global property level (http://www.daml.org/2000/10/daml-walkthru):

<rdfs:Property rdf:ID="child">
 <daml:inverseOf rdf:resource="#parent"/>
</rdfsProperty>

That's nice, however, in realistic application scenarios
expressing inverse relations has to be restricted to specific domain /
ranges
of relations, as for example it is possible in F-Logic:

FORALL Org1, Proj1
 Proj1:Project[financedBy ->> Org1] <->
  Org1:Organization[finances ->> Proj1].

How is this reflected by DAML?

Regards,
Alex
