Yes, it's a bug. A return value of a function was not used; this
caused a lookup for the @noNamespaceSchemaLocation attribute to fail.
I used @schemaLocation for the few tests that I ran with XSI-driven
schema acquisition, so actually @noNamespaceSchemaLocation was never
tested :-(

Fixed now in CVS, xmlschemas.c revision 1.182.

Thanks for the report!
