I don't spot any in the formal or >informal parts of the DTDs. http://www.niso.org/standards/resources/Z39-86-2002.html#FileReq for instance. Thats the central navigation file.

E.g. there are 767 pages in the latest Harry Potter book, info derived from that metadata, sourced at book build time. regards daveP
