I apologize if this is a double-post, my initial reply did not make it
to the list.
Looking for input regarding this [possible] bug:

This might be a bug in libxml2 as your schema validates with the w3.org
validator[1].
If you look at xmlschemas.c, the actual line generating the error is
located at xmlschemas.c:15161
if ( (WXS_IS_LIST(type) || WXS_IS_UNION(type)) &&
(WXS_IS_RESTRICTION(type) == 0) &&
here--> (! WXS_IS_ANY_SIMPLE_TYPE(baseType)))
Simple-type macros are defined at xmlschemas.c:227:
#define WXS_IS_SIMPLE(item) \
((item->type == XML_SCHEMA_TYPE_SIMPLE) || \
((item->type == XML_SCHEMA_TYPE_BASIC) && \
(item->builtInType != XML_SCHEMAS_ANYTYPE)))
#define WXS_IS_ANY_SIMPLE_TYPE(i) \
(((i)->type == XML_SCHEMA_TYPE_BASIC) && \
((i)->builtInType == XML_SCHEMAS_ANYSIMPLETYPE))
As you can see, the macro in question verifies that the type is an
XMLSchema built-in type or anySimpleType. I believe the marcro used in
the test at line 15161 should be a combination of WXS_IS_SIMPLE and
WXS_IS_ANY_SIMPLE_TYPE, i.e., something like:
#define WXS_IS_SIMPLE_TYPE(i) \
(((i->type == XML_SCHEMA_TYPE_SIMPLE) && \
((i->type == XML_SCHEMA_TYPE_BASIC) && \
((i)->builtInType == XML_SCHEMAS_ANYSIMPLETYPE)))
Does this look like a valid diagnosis, or am I missing something?
Thanks,
Piotr
