How would you specify an XER encoding to XMI (http://www.omg.
org/technology/documents/formal/xmi.htm)? For example, an instance of the example 
PersonnelRecord at http://asn1.elibel.tm.fr/en/xml/ASN1-as-an-XML-schema-notation.
htm could be encoded in XMI as:

<PersonnelRecord dateOfHire="19710917">
  <PersonnelRecord.title>Director</PersonnelRecord.title>
  <PersonnelRecord.name>
    <Name>
      <Name.givenName>John</Name.givenName>
      <Name.initial>P</Name.initial>      
      <Name.familyName>Smith</Name.familyName>
    </Name>
  </PersonnelRecord.name>
  <PersonnelRecord.nameOfSpouse>
     <Name givenName="Mary" initial="T" familyName="Smith"/>
  </PersonnelRecord.nameOfSpouse>
  <PersonnelRecord.children>
    <ChildInformation dateOfBirth="19571111">
      <ChildInformation.name> 
        <Name givenName="Ralph" initial="T" familyName="Smith"/>
      </ChildInformation.name>
    </ChildInformation>
    <ChildInformation>
      <ChildInformation.name> 
      <Name givenName="Susan" initial="B">
        <Name.familyName>Jones</Name.familyName>
      </Name>        
      <ChildInformation.dateOfBirth>19590717</ChildInformation.dateOfBirth>
    </ChildInformation>
  </PersonnelRecord.children>
  <PersonnelRecord.number>51</PersonnelRecord.number>
</PersonnelRecord>

The XMI encoding allows MOF-attributes to be either XML-attributes or XML-child 
elements whose tagnames use a dot notation; normally you produce one form but you 
have to read either. Would there be XER rules that map this encoding to and from 
the example ASN.1 type definition?
