No problem with you moving this back online (I wanted to check that I
wasn't putting words in your mouth first).
Thanks for the clarification. I spotted you had reverted some recent
changes (thanks) but wasn't aware that restriction:hgv was also a recent
addition. I think deprecating these would be step in the right direction
and removes many of the concerns I had with using a new tag (namely you end
up with "applies" type data within both "restriction:hgv = " and
"applies="/"condition="/whatever the new tag is called).
I suggest we write up a wiki page proposing the changes. That way we can
better track the discussion :-)
p.s The talk page for Turn Restrictions is stupidly long. Will take a while
to work through it to see if there are any helpful tips in there!
