Here's the contorted logic I'd use to interpret this:

0 < 90.  Therefore the negotiated value would be 0.  This would mean
that neither party should send keepalives, etc.  However:

:   If the Hold Time field of the OPEN message is unacceptable, then the
:   Error Subcode MUST be set to Unacceptable Hold Time.  An
:   implementation MUST reject Hold Time values of one or two seconds.
:   An implementation MAY reject any proposed Hold Time.  An
:   implementation that accepts a Hold Time MUST use the negotiated value
:   for the Hold Time.

If I want to use keepalives and you don't, I'll send a notification.
Thus, regardless of whether or not the negotiated value would be zero,
it must still be acceptable to both parties.
