I guess. But more precisely, I think they could be described as
having the following characteristics:

  - a way for a Web application or document to cause a browser to
    tell a device it's running on to initiate a location query;

  - the results of the location query are returned to the browser
    from the device as a set of parameters representing the
    current latitude, longitude, and altitude of the device

  - the browser assembles those parameters into a query string, in
    a (semi)standard/expected form, which it then sends as part of
    a request to server running whatever Web application is
    specified (by the Web application or document that initiated
    the query) as the target that's expected to process the
    location data

  - (just as an aside) the Web application that's the target
    expected to process the location data may be the same
    application that initiated the query -- or it could just be
    some other, 3rd-part app that groks getting an HTTP request
    with a query string in the expected form

It is in the KDDI/Au case also. The results the two different
markup mechanisms/syntaxes produce are essentially the same.
