Hi all,

Is it correct that it should look for markers on the current page and if page 
boundary is current page then stop there. If boundary is page-sequence then 
keep going backwards on each page until a marker is found or reaches the start 
of the page-sequence and similarly for the document boundary.

I'm trying to work out exactly how the markers should work.
For the first starting within page and last ending I am fine with. First including 
carry-over seems okay.

Last starting within page is a bit confusing. A statement [1] in the spec suggests 
that it shouldn't really find the last starting in the page but rather find the 
node to the root in the area tree that is the last starting area. Another statement 
seems confusing but maybe this is if it is searching previous pages.

So if this was in a page then block "a" would be the last starting in the page.

<block id="a">
  <block id="b">
  <block id="c">

But if there is a column break in pos1 the last starting in page will become 
block "c" as block "a" is not starting in that part of the area tree.

If this is the case then there are two possible cases when starting an area: isfirst 
and other. When finishing an area there are: islast, (had) isfirst and both. This will 
supply enough information to add only the needed markers to the area tree. These 
markers can then be kept for later retrieval.

[1] "Every area in the hierarchy is considered preferential to, or "better" than, any 
area below it in the hierarchy."

[2] "If there is no such area, then the last qualifying area in the containing page is 
better than any other area."
