----------------------------------------------------------------
This is absolutely right, the burden is more on the Projects outside of Karaf.
For example Pax Web doesn't provide the capabilities because the
maven-bundle-plugin doesn't generate it.
For Karaf itself we have a hack, that generate the information before the
maven-bundle-plugin fills those templates for the manifest entries.
So in this case if a bundle adds the require capabilities for the http-service
it isn't installed even though Pax Web itself providing it, but not populating
the resolver "registry" with it.
This is something we need to take care of, maybe generate the
provide-capabilities on the fly for services even though the bundle itself
doesn't have that information attached.
