Exactly. 
What I am (slowly) trying to put together is a helper or configuration maker for CAPsMAN/CAPs:
CAPsMAN - CAP VLAN configuration example on help.mikrotik.com
but without exact lists there is the risk (remote as most and more common countries and cities are correct anyway) that the output will be something that will be rejected by RouterOS, nothing that someone with a little experience cannot correct/fix when it happens, but since the whole idea of such a helper is its use by newbies, it should be as foolproof as possible.
The best solution would be if the good Mikrotik guys would publish on manual.mikrotik.com the actual list that they use both in CLI and in Winbox, this way one would have a sure method of validation.
