I thought the markers only apply to the current page but I haven't
really looked into it. If it does apply to pagesequence/document then it
should be on the page viewport like the id references, so that the page
can be removed leaving relevent information for use later.
There may be other places to keep the markers but the area tree might be
easier to keep track of.

Page numbers would be good.

I think that you only need at most four markers of a particular class
per page, so if it is a dictionary type case it doesn't need all the
markers in the middle of the page with the same class.
