practices are among the most obvious..." are beneficial to achieving
accessibility.  They agree that without proper integration the result may be
obvious discontinuity and can affect user acceptance - but, none of the reasons

definition of Priority 1: essential to...  The developers agree it is beneficial
and at best important ...  After all, we're creating accessible pages today
without integrated tools.   Proposal to lower to priority 3
