I am not sure about this use-case. Why would you want to do such thing?
Can you please elaborate?

Again, I would like to understand more about the use-cases you are
thinking.

Before moving further with the discussion, would you like to detail the
behavior of getNamedFlow(flow_identifier) method? Is this method supposed
to stay on the Document interface? What should return this method in the
case you are calling with a flow_identified that does not exist at the
call time?

Cheers,
