Raymie Stata commented on AVRO-1006:
------------------------------------

On the one hand, the "Parsing Canonical Form" as I've defined it has important 
uses and I think should be part of the Avro system.

On the other hand, it's a good point that there may be additional canonical 
forms that satisfy different needs in the future.  The class- and method-names 
of the previous patch implicitly assumed a single canonical form.  I've 
modified the patch with new names that will better support the addition of new 
canonical forms in the future.  (I think I also fixed the Forrest problems, 
although I haven't been able to verify.)
