Thanks to everyone who replied. Perhaps if I'd been looking for the correct construct I would have found it in my files.

I've had this error when the input doc is empty, or when a BOM has
crept after the source has been saved using Notepad (although that was
specific to a certain XML parser, which I can't remember).  I guess
you could always use select="document(base-uri(/))"

What is the reason for using select="document(...)" instead of just select="/" ?
