My turn to apologise now ;-)

My text was written before the F2F so doesn't reflect any decisions made 
  there. However, it looks to me like it is still consistent with the 
text in the latest editors copy. Do we need to open a new issue to 
address your concern or is it covered by one of the outstanding ETF issues ?

You would prefer item 4 to remain in the encoding section then ?

Not sure, it's certainly legal in the encoding to have a "non-inline" 
element referenced only once within the serialisation tree. Also, any 
element with an id attribute _can_ be referenced from multiple 
locations. Perhaps we need to drop the multi/single reference 
terminology and just go with inline/non-inline ?

The mention of the RPC section in the proposed text was intended to 
fulfill your latter point - do I take it that you withdraw your initial 
objection or is some rewording necessary ?

Issue 48 captures this I think.
