Maybe I am misinterpreting the spec. Looking at volume 1.2.1 of the
spec, 11.4.2.1, it says:

"If the status of the operation that generates the Work Completion is

undefined except as noted below. The contents of a Work Completion
are:"

Then it lists the reported fileds with wrid first and the opcodes
following.
