Hi Erik, 

I think it is not lax. 
I think it is strict except that type libs are imported in a way that
makes them be applied in a lax way. 

If you say lax validation, and you have a schema for a namespace that
contains top-level element or attribute declarations, then undeclared
elements in that namespace will not be flagged as errors because the
mode is lax.  This is not desirable. 

If the schema for a namespace contains top-level element or attribute
declarations, then that structural validation should apply.  So if
instance data contains elements in the namespace that are undeclared by
the schema, then a validation error needs to occur. 

We only want to switch to lax mode when the schema for a namespace
contains no top-level element or attribute definitions since in this
case one is guaranteed to always fail validation, but such a schema is
useful for providing a type lib that declares no structures.

Ok great! I really didn't like this special case. So this should come 
down to saying that the validation mode is lax, right?
