The warning is emitted because the hash keys returned by ctl2_hash_guid()
for IXMLDOMSchemaCollection2 (50ea08b0-dd1b-4664-9a50-c2f40f4bd79a) and
ISchema (50ea08b4-dd1b-4664-9a50-c2f40f4bd79a) are the same. It seems to
me a bit inadequate that ctl2_hash_guid() does 'return hash & 0x1f'. But
I think that fixing this problem is outside of the scope of my patches
and deserves a separate investigation.
