I meant the spec. OGC has developed a silly click-through license that
I have trouble parsing. It's either entirely benign, in which case why
is it there? Or it requires me to make sure that anyone I might pass
the spec on to must agree to the click-through, in which case the spec
is not particularly useful to me.

Post the spec somewhere w/o the click through and I'm a happy camper.
