[xml] xmlReconciliateNs interface per node

[George Georgiev <george georgiev sf gmail com>]

Hi,

I have a scenario where I am combining xml elements from a number of
documents. The documents are heavily namespaced and it looks
xmlReconciliateNs does not scale well.

It will be nice if xmlReconciliateNs and xmlDOMWrapReconcileNamespaces
are fixed to scale better, but I have an idea for an extremely
straight forward change that also will help me to resolve the problem.

If I have an additional interface xmlReconciliateNodeNs(xmlDocPtr doc,
xmlNodePtr tree, xmlNodePtr node) that I could call per element will
allow me to avoid the scalability problem of xmlReconciliateNs and the
change in the implementation will look as simple as:

+++ b/tree.c

(END)

Please let me know is this sounds reasonable or I could do something
else to avoid the problem?

Thanks,
