Support for XML Schema xsd:appinfo

[daheater]

I am attempting to model the ARINC Specification 816 XML schema.  The spec uses the xsd:appinfo element in the xsd:attribute element to indicate the attribute position as such:

<xs:complexType name="ApronElement">
 <xs:annotation>
   <xs:documentation>
     DO-291/ED-119-AM_ApronElement
   </xs:documentation>
 </xs:annotation>
 <xs:attribute name="numberid" type="Count" use="required">
   <xs:annotation>
     <xs:documentation>
       Feature identification number
     </xs:documentation>
     <xs:appinfo>
       AttributePosition="1"
     </xs:appinfo>
   </xs:annotation>
 </xs:attribute>
 <xs:attribute name="idobject" type="xs:string" use="required">
   <xs:annotation>
     <xs:documentation>
       idapron (name of apron).
     </xs:documentation>
     <xs:appinfo>
       AttributePosition="2"
     </xs:appinfo>
   </xs:annotation>
 </xs:attribute>

Can this be done in EA?  And, if so, how?

Thanks
Greg
