I don't think there is a way to extend an already declared attributeGroup with
more attributes. However, if you create a new attributeGroup you can reference
another attributeGroup within the new one:

<xs:attributeGroup name="Y">
   <xs:attribute ...>
   ...
</xs:attributeGroup>

<xs:attributeGroup name="X">
   <xs:attribute ...>
   ...
   <xs:attributeGroup ref="Y">
</xs:attributeGroup>
