if node can get at the xmlDocPtr (owner document?), then user_data
shouldn't be necessary, should it? (unless there's no private data storage
in the docPtr).

The problem with the other callbacks is that in a parse phase they don't
recieve anything telling you *which* parse phase you are in (i.e. the
xmlParserCtxtPtr). Same for the XSLT callbacks.
