RE: document() and fragment

Looking again at the spec, you're probably correct that
document("doc.xml#text") should build a tree representing the entire
document, and then return a reference to the element with ID "text", rather
than building a tree rooted at the "text" element. The current design is
essentially a side-effect of the way that Saxon implements embedded
stylesheets, and is handy because it saves memory when you only want access
to a small part of a secondary input document. For the effect that you want,
I'd suggest you avoid using the fragment identifier (they aren't very
portable anyway), and instead use the id() function to select the nodes you
want within the retrieved document.
