When the CreationFlag was not mandatory, behaviour was stated as 
implementation dependent if the flag was left undefined. The consensus 
was that it wasn't right to leave it implementation dependent. And since 
as a general approach we have chosen not to specify 'default default' 
values (we cannot say what is default for the grid) the flag became 
mandatory.

I guess the main question (for me) would be whether the values defined 
for this flag at the moment (including 'dontOverwrite' which is not in 
the spec but is in the latest schema) cover the behaviour most people 
would want to specify. Obviously, whether this flag is mandatory or not, 
it is still possible to specify a value that is not supported by many 
systems. That only means that the job can only be executed in the, very 
restricted, environment that supports that option.

We should probably provide informative text in the spec. on what we 
think is a reasonably common choice for this flag.
