We might ultimately need a Region interface that doesn't depend on Node though, especially if anonymous regions end up becoming commonplace. This is one of the reasons I think we need to think about this stuff a bit more.

What about we do the following:

a. Make the current supplemental interface in '6.2' be a 'Region' interface
b. Make NamdeFlow.getRegionsByContentNode return a list of Regions instead of  a NodeList. If the region happens to be an element, it will just implement the Region interface.
c. add the regions attribute as Mihnea suggests on NamedFlow, but make that a Regions list, not a NodeList.

That would keep the 'regionOverflow' attribute and the getRegionFlowRanges on the 'Region' interface and it would have the advantage of working with elements and pseudo-elements alike (e.g., if the region is '::before' or a ::slot mechanism when we define one to create regions).
