									<xs:documentation>The complete document identifier to be used by metacat.  The docid is a compound element that gives a scope for the identifier, an integer local identifer that is unique within that scope, and a revision.  Each revision is assumed to specify a unique, non-changing document, so once a particular revision is harvested, there is no need for it to be harvested again.  To trigger a harvest of a document that has been updated, increment the revision number for that identifier.
