Add explicit comparison of SPARQL 1.2 and RDF 1.2, vs SPARQL 1.1, RDF 1.1, and RDF 1.0. Might also want specific difference with SPARQL 1.0.

This specificity may not be needed for users who have never before encountered RDF or SPARQL, but I think it helpful for users who have worked with any previous version(s) — like me.

Note that we do discuss changes to RDF in the Abstract:

RDF 1.2 introduces triple terms as another kind of RDF term which can be used as the object of another triple. RDF 1.2 also introduces directional language-tagged strings, which contain a base direction element that allows the initial text direction to be specified for presentation by a user agent.

RDF 1.2 Concepts introduces key concepts and terminology for RDF 1.2, discusses datatyping, and the handling of fragment identifiers in IRIs within RDF graphs.

RDF 1.0 did not have named graphs, and therefore a discussion of the use of IRIs for graph names is not appropriate. (SPARQL 1.0 had it's own concept of named graphs).

It's all SPARQL specs which is why it says SPARQL 1.2.

The link is provided because that is the starting point. Arguably, the link could be removed.

Better to remove this.

RDF 1.0 didn't mention datasets at all nor were they concurrent.
This is a note. RDF 1.1 is 10 years old.
