I think you are assuming a consistency that doesn't exist. There are no 
"implied tags" in OSM; there are certain tags that, in certain countries 
and according to a reasonably big group of mappers, imply something else 
but this is far from a hard rule that could be baked into a "parseable 
data file".

You are assuming that "implied tags" are a widely known and used concept 
and that there are certain logical rules for that. There aren't, to my 
knowledge.
