Is it within the EPUB 3.0 specification to have a pagebreak span without an id?
I.e.
<span epub:type="pagebreak" title="2"></span>

I don't see any mention of it here: idpf.org/epub/vocab/structure/#pagebreak or here: idpf.org/accessibility/guidelines/content/xhtml/pagenum.php. All examples in the spec do include an ID though. Is there a reason why you don't want to include it? – Jason Down♦ Jun 13 '16 at 14:48
Pagebreaks are usually used in conjunction with nav document page-list sections and since you need an id to refer to pagebreak markers in the book it'd be rather pointless to use pagebreaks without ids and a corresponding page-list section.
You can find an IDPF-approved sample epub3 book with pagebreaks and a page-list nav section here.
