document nodes are not element nodes.

Those appear to be implementations built upon existing parsers. One even 
happens to be using libxml2. I still say that the xml:base 
clarifications in the GRDDL specs are specific to GRDDL. The current 
behavior of the existing XML parsers are correct in respects to how they 
handle base uri. When writing an implementation for GRDDL, you would 
need to use the base uri of the document element rather than from the 
document node in order to conform to the GRDDL specification in terms of 
the document's base uri.
