Thank you for your interest in XSL.

Unfortunately, while the XSL FO SG realizes that it 
would be useful to be able provide a z-order to the
various regions, the SG has decided that this must
be considered outside the scope of the (already
much delayed) XSL 1.1 spec.

We have put the issue of providing z-order to regions
on our list of post-1.1 considerations.  In fact, the
plan is for a future XSL version to have a more complex 
page master FO that should address these and other issues.

for the XSL FO SG

	Hello XSL Editors,
	 
	The XSL FO Specifications 1.0 and 1.1 do not specify an order
regions are placed on a page. The order of regions is quite important
when regions are overlapping or some object is placed out of a region.
Currently, an ordering of regions is only supported with Antenna House
XSL Formatter in the following way:
	 
	An order of regions on a page is specified in a
simple-page-master by the order of description of region. For example,
let simple-page-master specify 3 regions:
	 
	<fo:region-before ...> ... </fo:region-before>
		<fo:region-body ...> ... </fo:region-body>
			<fo:region-after ...> ... </fo:region-after>
		 
	Then the region-before is placed on a page, then the region-body
is placed, and after that the region-after is placed. This order allow
put watermarks in a header. I think this very convinient and useful in
many cases.
	 
	For this example, Apache FOP ignores an order of regions and
always places regions in the order they should be specified, i.e.
region-body, region-before, region-after, etc. RenderX XEP produces a
warning that region order is incorrect and works as FOP. 
	 
	The proposal is the following:
	 
	The order of regions in a simple-page-master can be any. This
order specifies an order regions are places on a page produced with this
master.
	 
	I think this proposal is easy for emplementation and it can be
included into XSL FO 1.1.
	 
	Sincerely,
	Alexander I Rozhenko
