Re: [Geopriv] draft-rosen-geopriv-pidf-interior

Brian - Specifically to the example you quote

"The airport manager want to give you terminal/councourse/gate, not
building/unit/room, or maybe the terminal is a separate address, the
"concourse" goes in "BLD" and the gate goes in UNIT. See the problem?"

In products that show graphical representations of a terminal it is
obvious the terminal is the building; concourse the floor (where the
floor is represented by a floormap of the concourse) and gate is an area
within the floor.

There is no problem using the existing civic tags.

I'm not trying to suggest INT tags are not useful for localization of
the base tags in PIDF-LO where a local tag name may help certain
applications. If we can think of your proposal as a mapping that can be
used by certain applications, rather than a replacement I'm more
comfortable with that approach.

That way we get the best of both worlds. No?
