Do you want one key value that is the concatenation of the two attribute 
values?
Or do you want each attribute value to serve as a key?
In the latter case you can simply do
    use="@oid, @parent-oid"

In the first case you will need to concatenate with a separator 
character which you know will not be in any attribute value.
