implementation issues

   Hello,
   I am new to this list so please do not be harsh. I am doing an 
implementation of sieve as described in rfc 3028, without any extensions 
other than the ones described there. I have some questions which were 
not answered by the rfc:
   - if I have several actions in a block except stop, I accept only 
fileinto and keep, and give an error message for any other combination 
of 2 or more (like keep, discard or redirect, discard). Is this wrong?
   - if I have more actions after I filter a message and several tests 
are true, such that several command could be executed like keep and 
discard, what do I execute?
