SAX expects namespaces to be issued _BOTH_ as prefix mappings and as attributes. Many applications rely on that and use just one or the other, whichever is most convenient, rather than burning cycles redundantly checking both. In fact, the SAX spec notes that start/endPrefixMapping is mostly there for streaming applications which need the namespaces defined before the attributes are processed. I believe our code currently responds to the attr rather than the prefix mapping, which would explain why your attempt to pre-establish a namespace wasn't being honored. I believe we do generate both events on output, though; if not, that's a genuine bug and we should fix it. We've discussed changing the input side of things to accept startPrefixMapping() and deal with the possible redundancy. I'm not sure what the current state of that debate is. Meanwhile, have you considered simply modifying your stylesheet to generate the proper namespace declaration on output? Or do you really need to set that programmatically on the _input_ to the processor?
