ALTER XML SCHEMA COLLECTION [.]
ADD { | }
I would not be at all surprised if the functionality of this is boosted a bit in a later service pack, but, in
the meantime, let me stress that this is a tool for adding to your schema collection rather than changing
or removing what’s there.
DROP XML SCHEMA COLLECTION

DROP XML SCHEMA COLLECTION [.]
