modification in schema

[lesidaner]

In the current xsd for 2.1 there is a mistake
<xs:attribute name="version" type="xs:token" fixed="2.0" use="required"/>
it should be at least
<xs:attribute name="version" type="xs:token" fixed="2.1" use="required"/>

I have a proposition of modification :
As we it's a minor version evolution retro compatible the 2.1 validator, should also be able to validate 2.0
we can write instead
<xs:attribute name="version" use="required">
xs:simpleType
<xs:restriction base="xs:token">
<xs:enumeration value="2.0"/>
<xs:enumeration value="2.1"/>
</xs:restriction>
</xs:simpleType>

To be discuss what should be the more accurate
