I could swear this came up somewhere recently, but right now I can't
find it. In XPath 1.0, what does the id() function do if there are
multiple elements in the document with the specified ID? (This is
possible, even though invalid.) Should it:
1. Report an error?
2. Return the first one in document order?
3. Return a node-set containing all of them?
4. Something else?
