[xep-support] Correct Behavior For reference-orientation on simple-page-master

[W. Eliot Kimber]

Continuing to try to understand reference orientation, it appears that 
XEP 3.03 is not correctly implementing reference-orientation on 
simple-page-master. The diagram in the FO spec 
(http://www.w3.org/TR/xsl/PageAndRegion-bodyWithOrientationOnPage.gif) 
seems to be clear that reference orientation should not result in the 
rotation of the physical page. That is, the absolute orientation of the 
page length direction and page height direction is unchanged by 
reference-orientation.

However, XEP does change it, such that if I have this page definition:

<fo:simple-page-master master-name="orient-0"
     page-height="11in"
     page-width="8.5in">...

Then the before edge is the physical top of the page, that is, portrait 
orientation).

If I add reference-orientation="90" then the before edge should be the 
physical left of the page, with the page still oriented as it was before 
(portrait). However, when I format this with XEP, the physical page is 
rotated along with the edges, making the before edge the physical left 
edge of the page, but putting the paper in landscape orientation.

That is, the absolute orientation of the page width and height should be 
invariant regardless of the reference orientation of the page master.

Cheers,

Eliot
