I think your wrong; see Table 4.8 (SANE standard 1):
"The setting of an option may affect the /*value*/ or /*availability*/ of one
or more other options."
There were at least a few people who asked about this on the list (/me
included), and the answers were always different :-)
Therefore I agree with Henning, that a better explanation is needed.
