[IDV #MVI-449737]: IDV - Data Chooser data type default

The defaults that are used are defined in a set of  external xml resource 
files. It is possible to
define your own defaults and override the system defaults. Before we explain 
how to do that we 
(Don and I) need to possibly change how we prioritize what default value to 
choose among the set
of defaults files.  

Also - it might be that we just need to add and/or change the defaults we have 
defined in the
system defaults for the imagery you are accessing.

We'll get back with you on this later this week (Don is out for a few days).
