Somehow it seems like we want to do a linked-list pattern like
rdf:value, rdf:next as in rdf:List...

Unless we have stores that natively understand compound shapes
expressed in RDF or *ML (I think the answer is "not really") the
simplest thing that could possibly work still seems to me to be to
just use WKT which is understood by pretty much every spatial query
library.

What is the compelling argument for expressing this type of data
directly in RDF?

Even the case of annotating, e.g. a segment of a LINESTRING can be
done easily enough by just writing down the segment as WTK and
annotating that...
