I failed to send these comments yesterday.

Section 10.1

* "The natural RDF literal is a mapping to typed literals." - Since the
natural RDF literal for SQL string types is plan literals, this does not
seem correct/useful as an introductory statement.

* "This section informative summary of XSD lexical forms..." - The grammar
of this sentence seems broken.
