What do you mean by breaking the spec? Local regulations come first and
whatever is to be used to transmit better comply with those no matter
what the IEEE 802.11 standard says. Just using a different rate
algorithm may not be enough to handle this kind of cases. There needs
to be a way to enforce some rules like the maximum continuous
transmission at a lower layer and somehow adjust the parameters if
needed.

This particular rule may not be too much of an issue for now since it
came up in a case where non-standard TX rate were used (i.e., something
below the minimum used in 802.11a). Anyway, we should try to be able to
handle whatever rules comes up now or in the future. Of course, one way
of handling limitations is not to allow transmissions at all, but that
may not always be the ideal solution.
