Seems to me that requiring that the computer or human needs a lot of background knowledge about how the context is determined is a bad thing, given that putting the context in the key (and thus removing the ambiguity) is easy. > piste:lift:occupancy -- wtf? this can only ever happen on a piste:lift > right? there is absolutely zero point in this tag.. call it occupancy > -- the result is 100% identical.

The only thing > this does is make the tag name very long, Of course it serves a purpose - it tells you that the value of the tag describes the occupancy of a lift. An "occupancy" tag could be used to describe attributes of different types of object - number of people in a building, number of fish in a pond, etc. Without the name space you need to get the context from somewhere else (one of the other tags... which one?) to make it meaningful. > and add a pile of annoying colons.

The chance of them remembering the key is probably reduced, Or the chance of them remembering which tags can be applied to which types of objects is increased because the tag name makes it clear what sort of object it will work with. > and the chance of them thinking it's ok to come up with new > unnamespaced tags is also reduced which will either mean they won't > propose things This is completely stupid - yes, they might avoid coming up with new unnamespaced tags and *shock* propose new namespaced tags instead.
