The 'IDL' approach has been found to be very useful to agree on the data
structures in & out and the semantics of an operation without getting
bogged down in rendering discussions.

Rendering this agreed interface is then found to be very simple. This is
exactly the process that has been used in doing the GLUE
specification... and that drifting off activity seemed to work out OK!
