One related question I have always had, if you look at the actual printed book, does the position of this tag end that page number or start that page number?
In other words using your example, is the
Code:
<span class="com-rorohiko-pagestaker-style">85</span>
put after the last word on page 85 or is it marking the start of page 85 material (before the first word on page 85)?
The reason I ask (other than the off by one page issue) is that I have seen ebooks that tried this based on where the physical page number was printed in the pdf (top header or bottom footer) which makes it even more confusing. There must be a convention.
