But none of this solves the problem that the information passed by the XML parser to the application needs to include information about the bindings of namespace prefixes to URIs, because there might be prefixes that the parser can't resolve because it doesn't know about them. So the application has to worry about prefixes, which inevitably complicates XML processing languages and APIs, and creates the opportunity (as in XBRL, thanks Ghislain) for applications to invent their own semantics for how prefixes are handled, which might differ from the semantics assumed by standard tools.
