I understand and sympathize.

Perhaps Step 2 could say:

         Selectively apply any or all discovered transformations to obtain 
GRDDL results.
         [N.B. Selection may be guided by the agent's capabilities, local 
security policies
         and possibly user/client intervention.]

Does that work for everybody? Dan? Chime?

I think that it expresses just enough to be meaningful and helpful
without getting bogged down in details that are not within our remit.
