Review 10-110r3 bibliography issue

[ronaldtse]

No "multiple bibliography section" markup was applied to solve the issue. The subsection markup (=== Recommended reading) was removed and put a boldface instead (Recommended reading).
The references of the bibliography (Normative references) render properly. But the Recommended reading subsection is not shown.

As I've already stated: currently the references section only renders bibliographic information, and nothing else. Clearly SDOs don't care about structure and put any random crap in their bibliographies, so I will relax that.

@manuel489 Bibliographies should now print any content they contain. Could you please review the documents this has come up with for you, and ensure that there are no unintended consequences? You will need to pull isodoc from github

... ALTHOUGH! I'm not sure what will happen with subclauses of bibliographies, and I will still be treating extraneous content as a grammar violation.

[opoudjis]

Ah, I also need to not strip extraneous material from bibliography in standoc.

Currently, standoc sorts biblio entries, then inserts them in sorted order after the title. It needs to do so at the location where the first biblio entry occurs in the given text.

In addition, any notes following bibitem needed to be sorted along with the bibitems.

normref_cleanup must not remove all content other than bibitems and title from Normative References; but the assumption will remain that any text before the first reference will by default be replaced by the boilerplate for normative references.
