Re: [CCAMP] rwa wson framework: multi-degree ROADM

Hi Giovanni, in the example given in section 5 (thanks to Dirk) we have 
multi-degree ROADMs. In section 3.3.1 we do mention higher degree ROADMs 
but refer readers to another draft. Hmm, maybe we should also point them 
to section 5. While I don't mind adding another picture, I think the 
chairs will be more interested in us reducing the length of the document 
than expanding it ;-) .

Cheers

Greg
