unset attribute (which is specified as being a valid sentence
attribute) gets L{None}.

L{None} does not appear in the sentence attributes of the
protocol, even though it's in the specification.
This is because L{None} is a placeholder for parts of the sentence you
don't really need or want, but there are some bits later on in the
sentence that you do want. The alternative would be to have to specify
things like "_UNUSED0", "_UNUSED1"... which would end up cluttering
the sentence data and eventually adapter state.
