[Talk-GB] Tagging maxwidth "Except for access"

[Colin Smale]

Hi,

Maybe I am just having a "blond moment" but I can't see any way of 
capturing access restrictions "except for access". Loads of country 
roads are signposted as "max width 6'6" - except for access" which 
implies a wider vehicle will fit (just). There are other restrictions 
which are sometimes qualified in this way, like "No HGVs except for 
access" but when they specify a class of vehicle then the tagging is 
obvious - in this case "hgv=destination". But this can't be done simply 
with maxwidth (and maxweight, maxheight).

As I can't see any direction on the wiki I thought I would let up a 
balloon here to see if anyone has come up with a tagging solution for 
this (in my experience) typically British phenomenon.
