This is great!  I would add one additional criteria.  That the XML is
kept in a seperate file so that changes could be made to the interface
without re-compiling.  Something like
$GISBASE/task_description/r.basins.file.xml.  This would allow very
rapid language changes (German, French, ...etc.) and user customizations
- just replace/edit the XML files.

Any developed interface systems should use the --task_description (I
changed the internal "-" in your original message to an "_") instead of
the raw XML.  Maybe --interface_description, since a user will probably
never type it?  And then change the XML directory name to match.

take care
