Thanks for your feedback.

My initial wondering was triggered by trying to pass the (open source,
oslc-tools) test suite, and noticing all the failing tests because our
implementation of the provider would use relative URLs in service
catalogs and likes.

Then I wondered, are we wrong, or has the test suite to be fixed :-/

I think I have to read the specs again and maybe figure out a proposed
wording to make it better... and will discuss with Steve if the test
suite has to be fixed on the relevant list.

Best regards,
