Technically, either approach to tagging would work. One question is which way results in the fewest number of mappers (and end users using the query tool) being surprised at the way the object is tagged/ The other question is which one gives the least undesirable results on renderers that support "ordinary" taxis but not the motorcycle ones. I think the best we can hope for from all this is that the OP mulls over all the arguments, does whatever seems best to him and also documents it in the wiki. As a side-issue, I'm not too worried if these discussions don't end up with a formal proposal but merely inform somebody's decision about "any tag you like." What does worry me is that these things then go undocumented and get used inconsistently. -- Paul
