Geoffrey,
    I also went back through all the LRMs and was surprised that nowhere

was the disabling feature described. And was further surprised when Marq

reported that even the Cadence simulators do not support the feature 
because I remember using this feature on occasion. I was so confident of

this that I described this feature in my book. I imagine what happened 
is that we forgot to describe this feature in the original versions of 
the LRM, and during some clean up of the LRM someone who was unfamiliar 
with the feature added the restriction that the direction must either be

+1, -1, 0, or unspecified, and that later someone at Cadence saw this
new restriction and removed the feature from Spectre & AMS Designer.

However, that is all beside the point now. The question remains: how do 
we provide an easy and efficient way to disable cross. There seems to be

two choices. Either use the direction indicator or add an additional 
argument. My preference is to use the direction indicator, but it is not

a strong preference.
