Subtle but important point is that what gets published to the ebXML 
Registry is not just pointers to above artifacts but the actual  
artifact. Pointers to externally managed artifacts are also supported 
but then you cannot  benefit from many of the lifecycle management and 
governance features of the ebXML Registry for these artifacts.

While the list of WSDL related queries being defined by the WS profile 
for ebXML Registry is still growing I neglected to mention a couple of 
other important queries supported:

-Find all WSDLs with Service implementations that use specified 
implementation platform (J2EE, .Net, ...)

-Find all WSDLs with Service implementations that use specified platform 
resources (Database, JMS, JAXR...)
