Re: Option to use 63 Fixed Stuff columns for payload

No functional changes are involved  --  this is an optional addition. I
will write the text for the necessary addition
after I have obtained a copy of the document.

The 63 columns of fixed stuff are required to accommodate WIS mapping.
I think we all agree on that.  When you talk about payload codewords, I
interpret this to mean a proprietary end to end signalling mechanism
in the SPE. That is, your not putting payload _data_ into these fields.

In my view, if you choose to "optimize" the SPE by adding a proprietary
protocol into the 63 columns which shall be specified as stuff, that
implementation falls outside the requirements for the standard since
there could potentially be a large number of codewords to which ALL
equipment would then have to respond.

In other words:  You can do what you want with the fixed stuff to
optimize the architecture of your design. You can not expect every one
else to be compliant with this implementation.
