[xep-support] Z-Index and Complete Support for Absolutely Positioned Block Containers

[W. Eliot Kimber]

Currently XEP only supports absolutely positioned block containers by 
positioning them relative to the page's reference area, not the nearest 
ancestor reference area (e.g., region-body reference area). Any word on 
when absolute positionging will be fully implemented? We're using it in 
one document type to overlay text or graphics on top of another graphic, 
e.g. (ignoring issues of dimension specifications):

<fo:block-container>
   <fo:block><fo:external-graphic src="url(mygraphic.eps)"/></fo:block>
   <fo:block-container
       absolution-position="absolute">
     <fo:block>PROOF</fo:block>
   </fo:block-container>
</fo:block-container>

This works great because the inner block container is positioned 
relative to its containing block-container. Without this I'd have to 
know exactly where on the page the outer block-container fell, which of 
course I can't know unless it too is absolutely positioned.

Also, any plans to implement z-index? Not a hard requirement since 
stacking order seems to be pretty well defined within a flow, at least, 
but handy for make sure you're 100% clear about what the result should be.

Thanks,

Eliot
