I don't think so. While it is true that an attribute group reference
doesn't correspond to any schema component, but the wording doesn't say
it's not allowed, and the synopsis does allow it. Also, it's pretty
clear from schema-for-schema that it is allowed. The fact that Xerces
allows it is yet another evidence that it is allowed.
(from s4s)
<xs:complexType name="attributeGroupRef">
<xs:complexContent>
<xs:restriction base="xs:attributeGroup">
<xs:sequence>
<xs:element ref="xs:annotation" minOccurs="0"/>
</xs:sequence>
<xs:attribute name="ref" use="required" type="xs:QName"/>
<xs:attribute name="name" use="prohibited"/>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
So I think this is a bug of RI (I already fixed it internally), together
with a bug of RI where it fails to produce an error message.
Unfortunately, the only workaround that I can think of is to work a
miniature transformation that strips away those problematic annotations
before you run it through XJC.
