Thanks a lot! I clear understand that it's a very complicated issue.
Is it possible to have a configuration parameter (in XPath context?)
that tells is inherited namespaces and "parent:" namespace support
enabled or not:  if this flag is set to "true" then libxml2 does add
all required namespaces and does correct "parent" lookup for namespaces;
otherwise it works the same way as now. I think that implementing
it this way will provide better XPath 1.0 support for applications
that will need this feature and in the same this will not impact anyone 
else.
