Ok, but you still have a potential conflict here. Hypothetically, you
could have a "timetable" tag which applies to both a bus stop (tells you
when busses arrive) and a post box (when is the post collected?). A neat
solution is to have "bus_stop:timetable" and "post_box:timetable".

That may be, but I still think in some cases you are going to want
multiple conceptual items attached to a single item - namespacing allows
this to be done without risk of conflicting tags and makes it more obvious
how the tags interact with each item (conceptual or physical).
The same thing _could_ be done with relations (i.e. you mark up the
physical items with ways and nodes and use relations containing physical
items to represent the conceptial things). But at the moment that would
be even more complex than a clear set of namespaces.
