Example 3 from the PREMIS Data Dictionary, abbreviated

What appears in the record:
<?xml version="1.0" encoding="UTF-8"?>

What I'm proposing the schema for the object entity should allow:
<?xml version="1.0" encoding="UTF-8"?>
<object xmlns="http://www.loc.gov/standards/premis/v1"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         <objectIdentifierType>LATMD</objectIdentifierType>
         <objectIdentifierValue>FD3OLGGY</objectIdentifierValue> <!-- the

     </objectIdentifier>
     [...]
     <objectCategory>file</objectCategory>
     [...]
     <relationship>
         <relationshipType>structural</relationshipType>
         <relationshipSubType>has part</relationshipSubType>
         <relatedObjectIdentification>

             <relatedObjectIdentifierValue>FD3OLGGY/gr-zip

             <relatedObjectIdentification>
                 <relatedObjectIdentifierType>LATMD</relatedObjectIdentifierType> 

                 <relatedObjectIdentifierValue>FD3OLGGY/FI.0610.homesales.eps</relatedObjectIdentifierValue>

             </relationship>
         </relationship>
     </relationship>
     [...]
</object>

There may be very good reasons for not doing this.  I just wanted to get 
your feedback.

Thanks,
Youn
