The note before the introduction is the abstract, and seems to be a
standard feature in articles. You are right though, some parts should be
shortened, information is repeated.

Table of contents will be produced by the build system when the article
is split into several pages (FORMATS=html-split), for my test I compiled

Thanks. I will add your links to a "Further reading" section.
P.S. Just realized I've sent this answer to your email only and not on
the list. Apologies. Also note my comment on table of contents is
