Hi Boris,
That sounds perfectly reasonable. I think that XQilla already does all
of those things, but it would be good to get it into Xerces-C too.

Hi John,
Another area where we can improvise the interface alignment
is DOMXPathNSResolver. I just had a quick chat with Alberto
and here are the changes that we both agree would make sense
(I hope the motivation is self-evident, if not -- let me know):
1. Add the ability to provide custom namespace-prefix mappings
in the DOMXPathNSResolver interface. Something along these
lines:
virtual void
setNamespacePrefix (const XMLCh* prefix, const XMLCh* uri);
The new mapping will override any existing one. If NULL or
empty string is passed as uri then the existing mapping, if
any, is removed.
2. Change the createNSResolver() function in DOMXPathEvaluator
to return read-write DOMXPathNSResolver (const right now).
3. Allow NULL to be passed to createNSResolver() in which case
empty DOMXPathNSResolver will be created (can then be populated
with setNamespacePrefix).
Let me know what you think.
Boris
