[Talk-GB] Fences & Hedges

[Brian]

I have been considering mapping some of the boundaries in my area but am not sure how to tag the very common combination of a barrier that consists of both a fence (wire or chain_link) and a hedge. 

As there can only be one barrier tag should I just pick one, or is there a more sophisticated way of dealing with this situation.

 In most cases the hedge, being bulkier, is the most obvious barrier, but within the hedge is a fence. Perhaps its not important, just so long as the existence of a barrier is shown?

I would appreciate some guidance.

I'm sure this subject this must have been raised before but I can't find an obvious way of searching the Talk-GB list; am I missing something?
Thanks

 Brian
