What does modelReference on wsdl:interface mean ?

Hi all,

Initially, the most useful application of modelReference on interface
would be related to categorization. Other uses could include making
links to OWL-S profiles or WSMO services to handle services developed
in WSMO or OWL-S (rather than having complete annotation within WSDL,
you can simply put a high level annotation on the interface).

In the future, ontologies may be developed to provide standards for
interfaces analogous to Rosetta Net's specification of PIPs
(operations).
