"In addition to the RepositoryItems, an ebXML Registry is also capable
of storing standardized metadata that MAY be used to further describe
RepositoryItems. Instances of such metadata are referred to as a
RegistryObjects."

The second sentence is not quite correct, so perhaps a slightly "softer"
wording will do: "Such metadata are provided by various kinds of
RegistryObjects."

Yes, I too have spend a couple of years explaining what "extrinsic"
objects are, but usually a brief explanation suffices to still the
rolling eyeballs :-)
