[TTML] named metadata item originatingSystem vs creationSystem

As part of my review of TTML2, I've noticed that the named metadata item
"originatingSystem" has been changed to "creationSystem".

To me these two labels are not synonymous, without further explanation. I
consider the originating system to be the system that created the first
version of the document, and the creationSystem to be the system that
created the current version of the document.

Perhaps this could be clarified by adding a revisionSystem named metadata
item in addition to creationSystem, and clarifying in the text for
creationSystem that it is intended to mean the originating system.

Other opinions on this welcome!

Kind regards,

Nigel
