Re: Application Headers

[Christopher Ferris <chris.ferris@east.sun.com>]

David,

Well, there are two aspects to this... 
1) the receiving "application" MUST be capable of processing the
namespace qualified application headers that are qualified with
a mustUnderstand=true
2) the receiving MSH MUST be capable of forwarding/providing
the namespace qualified application headers that are qualified with
a mustUnderstand=true to the receiving application

In either case there needs to be an exception/error reported.

However, since these are "application" headers, the "application"
needs to be notified... Hmmm... we may have a layering issue
to deal with here...
