I believe the correct implementation is to use the "no-value" tag
with a value length of 0. That's what CUPS is doing, and according
to section 3.10 of the current draft protocol document:
"If a value-tag contains an "out-of-band" value, such as
"unsupported", the value-length MUST be 0 and the value empty
ù the value has no meaning when the value-tag has an
"out-of-band" value."
(Carl-Uno, there seem to be 8-bit characters in the latest drafts,
like the "ù" on the third line above; some MS Word strangeness?)
