JaxMe (wrongly) accepts schema using <group ref="..." maxOccurs="unbounded"/>

JaxMe accepts (and generates faulty code for) the following schema:

<xs:group name="params">
<xs:choice>
<xs:element name="string" type="xs:string"/>
<xs:element name="int" type="xs:int"/>
<xs:element name="boolean" type="xs:boolean"/>
</xs:choice>
</xs:group>

<xs:element name="call">
<xs:complexType>
<xs:group ref="params" maxOccurs="unbounded"/>
</xs:complexType>
</xs:element>

However, it should give an error message about not supporting model groups with maxOccurs > 1, as it does with the following schema:

<xs:element name="call">
<xs:complexType>
<xs:choice maxOccurs="unbounded">
<xs:element name="string" type="xs:string"/>
<xs:element name="int" type="xs:int"/>
<xs:element name="boolean" type="xs:boolean"/>
</xs:choice>
</xs:complexType>
</xs:element>

Perhaps somewhat related to JAXME-61, but I think the correct behaviour would be to fail with an error message on the first schema above until support for groups with maxOccurs > 1 is working?
