I can't quite follow what you're saying.   I combined Seq and lists
because people said "we can't get rid of Seq unless we tell people what
else to use".   You say you want to deal with them separately, but ...
then it seems like you're saying we have to leave in one or the other --
which sounds like we have to deal with them together.

I can live with that, but I'm not sure why we'd say
dont-use-non-blank-nodes-for-Seq any stronger than dont-use-Seq.

Oh, yeah, I'd also *love* to stop using the terms "collections" and
"containers" and just use "Seq" and "List".   I know "Collection" is
hard-coded into RDF/XML, but still.    Expecting people to remember
container=Seq and collection=List is a bit ... rude.    Especially if
we're calling g-boxes "Graph Containers", which I've already seen one of
us mis-write as "RDF Container".
