For input like this:
...
<xsd:complexType name="x" />
...
when JaxMeXS creates an XSComplexType object, both
isRestriction() and isExtension() return false.
The XML Schema specification says:
[Definition:] Except for a distinguished �ur-type definition�,
every �type definition� is, by construction, either a �restriction�
or an �extension� of some other type definition.
Therefore, for type x, either isRestriction() should return true or
isExtension() should return true.
(Nothing in the documentation of methods isRestriction() and
isExtension() says that they don't actually represent the concepts
of restriction and extension from XML schema.
(Actually, the documentation contains errors, referring to some elements
even though the methods are on XSComplexType.)
Attached in a test program that demonstrates the problem.
This seems to apply to JaxMeXS in JaxMe 0.3.1, 0.4beta, and
the current default CVS branch (HEAD?).
