yes, this looks good.

The only thing missing to me is that the number of attributes is already
known but isn't returned here.  It would be nice to know that at this
point for initialising arrays once, rather than having to grow them as
each new attributeNs callback is invoked.  

Well, I'd actually like the lengths of all the xmlChar* to be returned
too, since you know them and the user app has to strlen() them again to
find out their sizes for copying.  Lots more strlen()ing than before
since you now have namespace URIs, prefixes and the localname itself
instead of just the localname.
