20713	Suppress validator warning for amenity within amenity for school	zelonewolf@…	team	"In cases where two different schools share a common grounds, it is typical practice to tag the overall grounds with an `amenity=school` polygon.  The overall grounds are either unnamed, or tagged with a `name=*` for the name of the overall complex.  The tagging scheme is supported by renderers as well; Carto renders `amenity=school` with landuse-style rendering.

Each school is then represented by individual `amenity=school` nodes with each schools `name=*` and other details.

This tagging scheme, which is in use, currently raises an ""amenity within amenity"" warning in the validator.  This validator finding has prompted a currently controversial[1] proposal[2] to introduce new tagging, ostensibly for the reason of making the validator finding go away.  Rather, it would be more appropriate for JOSM to suppress this warning for cases of `amenity=school`, `amenity=college`, and `amenity=university` -- OR limit the warning to cases where the `name=*` is identical between the node and the grounds.

A test case is attached demonstrating this behavior.
