RE: XQuery Update Facility Working Drafts

The insert statement as currently defined needs a node as insertion
target. Since you cannot insert a document node into any other node, you
cannot insert it using the insert statement. You should use a mechanism
that is specific to your environment to insert documents. E.g. in SQL
you would use the SQL INSERT or UPDATE statement to insert the XML
document into a cell...
