Yes. Otherwise you would need to add coordinate specification to the
file and use coordinate transformations for further processing. The
main purpose of the file is to specify an area for which other
specialized programs automatically create digital elevation model or
download surface map from map server. One such program might be
included in future therion (as an xtherion plugin perhaps).

Yes, it is planned.
