page-start
Processing instruction page-start identifies the location of page
breaks.
<?page-start?>
<?page-start page-number="2"?>
The location of page breaks in a final, paginated article should be indicated using
processing instruction page-start. The page number should be captured in a
pseudo-attribute page-number, which can be omitted if the page is
unnumbered. The page-start processing instruction can be placed at any
location in the article XML that is allowed by XML rules for well-formedness.
A page-start processing instruction should be inserted at the location of the page break between the first and second page, and (if the page is numbered) contain a page-number attribute the value of which is the page number of the second page. The start of
every subsequent page in the article should be identified in this manner.
It is normally optional to include page-start processing instructions.
However, page-start processing instructions are required in final files for
certain journals.
