Thanks Kasimier. I think I'll just move enumerations into attributes. A
little more complex for end users, but seemingly much better on the
schema end.

schema for schemata:
<xs:group
name="complexTypeModel"> <xs:choice>
<xs:element ref="xs:simpleContent"/>
<xs:element ref="xs:complexContent"/>
<xs:sequence> <xs:group
ref="xs:typeDefParticle" minOccurs="0"/>
<xs:group ref="xs:attrDecls"/>
</xs:sequence> </xs:choice> </xs:group>
So
either <simpleContent> or attribute declarations, but not
both. The attribute declaration goes into the
<restriction>.
An example would be the short hand form of
xs:anyType restrictions and the explicit form (although we have a
<complexContent> here).
Short
hand:
<xs:complexType name="myType">
<xs:attribute
name="attr"> </xs:complexType>
Explicit:
<xs:complexType
name="myType"> <xs:complexContent>
<xs:restriction base="xs:anyType">
<xs:attribute name="attr"
type="xs:string"></xs:attribute>
</xs:restriction> </xs:complexContent>
</xs:complexType>
