[jsdl-wg] Proposed Extension draft document

[A S McGough]

Michel, All,

In a discussion with a GridSAM user who has been asking for parameter 
sweep functionality for some time a use case came up that I'd not 
thought about before and it's not clear how we could do it with the 
current extension.

He has a use case where he wants to perform a parameter sweep using a 
program which takes a configuration file as the only input. The filename 
is always the same (lets call it input.data) and the program has no way 
to specify a different file name.

I can't see at the moment a way to deal with this without altering the 
file staging elements which then places a dependency between file 
staging and parameter sweep - not sure if this is a good idea. I suppose 
it could be done by placing a wrapper around the program... again not 
sure if this is good.

Any thoughts?
