Comment:

 I have implemented this in 25255, and welcome discussion on its merits.
 The final syntax/semantics I went with:

 <tag k="traffic_calming" v="yes" vmatch="*" />

 Means that any traffic_calming=* will be recognised, and the default value
 (unless set explicitly by the included dropdown) will be "yes"

 If vmatch is not "*", it is interpreted as a regular expression, so this
 works:

 <tag k="highway" v="motorway" vmatch="motorway(_link)?" />

 or, more simply:
 <tag k="highway" v="motorway" vmatch="motorway|motorway_link" />


 I think this is a useful extension, to solve a few peculiarities in the
 tagging scheme and to give us a bit of flexibility in decoupling the
 interface from the underlying tags. (With appropriate caution
 exercised...)

 It doesn't quite solve the highway=proposed, proposed=..., but it's a step
 closer.

 The same mechanism could also be used for <choice> elements of drop downs:

 <choice value="muslim" vmatch="muslim|islamic" ...>

 (Again, with appropriate caution...)
