Description

Currently xml:base is used when doing XInclude processing but not when processing XML Schema files (for @schemaLocation or xsd:include/xsd:import). The XML Schema specs don't mention xml:base (it wasn't ready at that time), so using xml:base for schemas does not seem to be strictly necessary for a processor.
Still, honoring xml:base for XInclude but not for Schemas creates the problem that the same relative path resolves to two different paths for XInclude and XML Schema (which might be used within the same document). This is at least confusing for the reader of a XML file.

My proposal would be to have a config option to honor xml:base for schema processing but leave the default behavior as is in order to maintain backward compatibility.
