In principle this is most likely fine, but I'd really prefer to have 
similar test for all node types that support this method, so we can move 
a check directly to node_get_owner_doc(). For those additional tests it 
would be better to add a new test function called 
test_get_ownerDocument(). Next step would be to make this test run on 
all document versions (3, 4 and 6), but that should be a separate patch, 
and I'm not asking you to work on it.
