Since attribuets can be versioned, we should simply add support for removing 
them at a specific version from the API, like we do for operation.

No special cases needed. It's simply a small limitation to fix.

Of course, that doesn't pre-empt the discussion as to whether we should simply 
decide to unilaterally break our backward compatibility. But I don't see why 
attributes would be special in this case compared to operations.

I think the reason we only added removal support for named operation is 
related to Leonard's goal of removing all named operation in favor of more 
restful APIs. (turn accessor/mutator into a property, searchable collection, 
POST factories, DELETE removal, etc.) 

Cheers
