Summary: Database Link Object for Docs & Collections

Initial Comment:
Provide a new object type that can be created within a Sedna database.  This Link object would allow a document or collection in another Sedna database to be accessed and operated on from the database where the Link was created.  For all statements (UPDATE, INSERT, XPath or XQuery, etc.)  performed on the Link the result would be same behavior as if the doc or collection existed in the same database, but the statement would actually be executed on the target which resides in a different database.   The Link to the target should be able to be designated as read-only or read-write.  If read-write is specified then data UPDATES would need to be synchronized for transaction integrity.

This new Link would allow the sharing of a large document or collection across several databases.
