Thanks to Bob and Harry for these very reasonable, rationale points.

SDP is a big mistake if it is not IPP with enhancements or it is
not the ALREADY STANDARD SDP: TIPSI. If neither IPP nor
TIPSI could not be enahanced to meet whatever the needs of a
server to device protocol, then what makes someone thing that they
can get a group of company reps together, start from scratch, and=20
get it right?! given that is what we have done several times now.

I feel that it is a reasonable embedded solution. Any "fixes" are just =
part of the
process now to move IPP/1.0 to 1.1 and beyond.
