Change to invocation.processSuccessful

In merging the change for #115 (process outcome), I made a substantive change to the description of the default value for the invocation.processSuccessful property:

 

Was:

 

                If this property is absent, its value SHALL be taken to be true if the exitCode property (§3.13.8) is present and has the value 0; otherwise its value SHALL be taken to be false.

 

Now is:

 

If this property is absent, its value SHALL be taken to be false if the exitCode property (§3.13.8) is present and has a non-zero value; otherwise its value SHALL be taken to be true.

 

Please reply if you disagree.
