fixed the pull of drs schema elements

Browse Source 
The previous code incorrectly assumed that attributes such as 
subClassOf come over the wire as strings. In fact they come over as 32
bit integers which refer to goversIDs. We have to post-process these
as it sometimes happens that a governsID comes over the wire before
the record that defines what it means.
