At the plenary, in discussion with Misha and Martin, it became clear that
there are two equalities needed.

The RDF specs need a mathematically rigorous and transitive equality. User
applications probably want an equality following John's proposal.

The RDF specs need to clarify that application developers are not misled
that the transitive equality is normative for all uses.

The RDF Core has agreed that the definition of equality is as I earlier
indicated, with exact (case insensitive) matching of lang-tags.

Misha suggested that we should use a note to clarify this.

Thus I propose that text such as the following is included near the
definition of literal equality:


NOTE: This definition of equality is appropriate when constructing an RDF
graph, when checking an RDF test case, and when interpreting an RDF graph
according to the RDF model theory. In other contexts it is usually more
appropriate to use the methods described in RFC 3066 treating a missing
language tag as "*".
