For <article>s which appear in journals there
is no container element to specify the name of the
journal that it appears in.
For this reason, it would be useful if there
was a new element named <publication> which
could appear as a child of <articleinfo>.
<publication> may also be applicable as
a child of <chapterinfo>, <sectioninfo> and
<part> in describing the name of the book or
set they are components of.
Typically publications have a title. Journals
also have a common abbreviated form of their
title. It would be useful to be able to
distinguish and choose the relevant form in
appropriate circumstances, either by
an attribute or by element content.
