Dbxml:lookup-index fails with edge-element-presence

Question

The custom xquery function dbxml:lookup-index seems broken for edge-element-presence indices when a namespace is specified:
dbxml> lookupedge edge-element-presence 'http://ceridwen.us/default' node11 'http://ceridwen.us/default' node1
1 objects returned for eager index lookup 'edge-element-presence'
dbxml> q "declare default element namespace 'http://ceridwen.us/default'; dbxml:lookup-index('test', 'node11', 'node1')"
0 objects returned for eager expression 'declare default element namespace 'http://ceridwen.us/default'; dbxml:lookup-index('test', 'node11', 'node1')'
dbxml> q "declare default element namespace 'http://ceridwen.us/default'; dbxml:lookup-index('test', 'node11')"
2 objects returned for eager expression 'declare default element namespace 'http://ceridwen.us/default'; dbxml:lookup-index('test', 'node11')'Dbxml-2.5.16, OSX 10.6.4

Is this what you need?
