It was a bug: if using the short-hand form as in "empty_1.xsd", the
content type "mixed" was incorrectly inherited from the base type
"anyType" .

Fixed in CVS, xmlschemas.c rev 1.119:

testSchemas --debug test/schemas/empty_1.xsd
Schemas: no name, no target namespace
Type: #CT1 [complex] content: [empty]
Element (global): internationalPrice

This didn't change anything for you, since the code is #IFDEFed together
with some other functions to be used to compute and restrict complex
types in the future; it will substitute some of the current code and add
additional constraints, which are still missing for complex types.
