I would find it very helpful to see a table of what sorts of XML

Hmm, but hierarchically structured documents such as XML don't map
well to a relational model. The former tend to be recursive (e.g.,
have more levels of containment than the one or two that might be
mappable to tables and columns.)

This mapping (relational model -> XML) is more straightforward.
