Hi Andrew, hi all,

Falko and I plan on implementing the subpacket in RNP (whether or not it 
will be merged upstream we can't say).

I also have quick question: Are chains for forward replacements supposed 
to be allowed, e.g. A claims to be replaced by B and B claims to be 
replaced by C? From what I read in the draft it should be allowed. In 
that case I'll have some feedback. If no chains are allowed, I'll have 
less feedback.

Best,
Johannes
