Right; Xerces supports the parts of the DOM specification that are 
XML-related. The parts dealing with HTML, XPath and schema 
information are not implemented. BTW, the support for DOM Level 3 is 
being updated as part of the Xerces 3.0 release.

The interfaces for the XPath specification have been placed inside 
Xerces to help the integration of Pathan, an open source project that 
adds XPath 1.0 and 2.0 support to Xerces.

I don't recall any functions with those names in the XML or XMLSchema 
specs; could you point me to the parts of the specifications where 
they are defined?

Could you be more precise? Which kind of memory are you referring to? 
(memory usage of DOM trees, memory used to validate XML, etc...)
