The best option is to filter attributes you don't want/need from  a source. Otherwise there's no big issue because you'd be forced to deal with multiple values one way or the other (per my conversation with Martin).

The Transform plugin just looks at one value at a time.

It can't be done in any plugin, really, short of maybe a really ugly filter function. I believe that fundamentally it's a multiple value issue generically, or something that has to be done as part of the header export step (but would be quite inefficient there). Eliminating the alias feature would address most of the inefficiencies.
