Actually the document() function in the current working drafts allows the URI to contain a fragment identifier, and if it does, the returned value may be an element node rather than a document node. This is the way document() is defined in XSLT 1.0. We've made a recent decision, which (if all goes smoothly) will be reflected in the next working drafts, to use a simplified version of the document() function for XQuery. This will not allow fragment identifiers and will not allow multiple URIs; it will always return either a document node, or nothing. Michael Kay
