This is an arena that has stovepipes everywhere. People's
understanding of "international" tends to be a product of
their experiences - that tend to be compartmentalized by
their associated institutions and career.
I strongly suggest this activity be characterized as a group that
develops an continuing understanding of the ecosystem and
the value proposition of TC CTI specifications. A starter diagram
is attached. The approach has worked well for NFV and CYBER.
Either this group or another adhoc one also needs to attend
to the large elephant in the room - ISAO formation and discovery
- or you'll find those "international" folks reticent on the uptake.
