Annotations for shared super class attributes and associations? [message #666804]

Suppose I have an abstract ECore meta-class called Cardinality with two integer attributes:
min:: EInt
max:: EInt

I have two subclasses that utilize the cardinality attributes:
ProductComposition extends Cardinality
RequestSpecificationComposition extends Cardinality

But the output XMI needs to use different tags to represent these instances as follows:

<xsd:complexType name="ProductComposition">
     <xsd:sequence>
          <xsd:element name="MaximumNumberOfComponents" type="xsd:integer" minOccurs="0"/>
          <xsd:element name="MinimumNumberOfComponents" type="xsd:integer" minOccurs="0"/>
     </xsd:sequence>
</xsd:complexType>

<xsd:complexType name="RequestSpecificationComposition">
     <xsd:sequence>
          <xsd:element name="MaximumNumberOfRequests" type="xsd:integer" minOccurs="0"/>
          <xsd:element name="MinimumNumberOfRequests" type="xsd:integer" minOccurs="0"/>
     </xsd:sequence>
</xsd:complexType>

How can I use annotations to vary the output format based on the subclass that uses the common super class attributes? The attributes are only defined once...so I can only place one Annotation on each attribute.
