I'm using libxml2-2.6.18 (and test case provided with it) and have
some question about element content type in xml Schemas:
- if I try testSchemas --debug empty_0.xsd then the content of both
complex type are empty which seems OK
- but if I try testSchemas --debug empty_1.xsd then the content of the
complex type is mixed : I'm wondering why this content is not empty.

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

I can't comment on this,

Reading the code to try to understand I have found
(xmlschemas.c:13261) a potential bug : if (base->contentType =
XML_SCHEMA_CONTENT_MIXED) instead of  : if (base->contentType ==
XML_SCHEMA_CONTENT_MIXED). I corrected this line, recompiled, but the
problem still exist.

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.

  that definitely looks like a typo bug, fixed in CVS, thanks !

Regards & thanks for the report,
