You issue while true is vague as to how it should be accomplished.  The new
text of this section is included below for your review.  Any help you can
offer to improve it would be welcomed.

Updated Section 3.2:

Page types

Pages and the graphic designs that create page layouts can vary in many
ways.  Pages can vary in orientation, size, side in view and order within a
printed document. Page layouts can have apply special treatments to pages
based on things such as the document's writing direction, the anticipated
printing treatment (double or single sided printing), or the planned
document binding technique, stapling for example. The following terminology
is used to describe pages and page treatments:

Page Orientation
The page orientation, or more simply orientation, is the page's orientation
as defined by a comparison of the length of the edges of a page box. A page
box has a long edge and a short edge. When a page box is a square the long
edge is the same length as the short edge, otherwise the page box is a
rectangle and the length of the long edge is greater than the length of the
short edge.

Portrait Orientation
A portrait page's height is greater than its width. Horizontal elements are
parallel to the short edge and vertical elements to the long edge.

Landscape Orientation
A landscape page's width is greater than its height. Horizontal elements are
parallel to the long edge and vertical elements to the short edge.

Front Side
Media used as a stack of sheets have two sides known as the front and the
back. The front side is the side in view. Typically, the user agent prints
on the front side of the media although it MAY place the page in an output
bin after printing so that the back is visible. Media used from a roll or
continuous form only have a front side. CSS does not provide a mechanism to
deal directly with the front and back sides, rather page layouts must be
designed in terms of left and right pages. 

Back Side
The back side of a sheet medium, is the side that cannot be seen when
looking at the front side. Typically, the back side is only used when
printing on both sides of the medium. Media from a roll or continuous form
do not have a back side

First Page
The first page in a set of pages. The UA determines which page is the first
page. The first page is generally printed on the front side of a medium,
however documents where the writing direction is right-to-left may cause the
printer to place the first page on the back side of the first sheet.

Facing Pages
Facing pages are two pages in order so that when viewed one page is on the
left and the other is on the right. For example, when a document is printed
with one page box per page sheet, on the front and back sides of the page
sheet and bound, the pages face each other. Page layouts for left-to-right
writing generally have the even numbered page on the left and odd numbered
on the right for documents. Other writing directions, as well as, printing
and binding treatments will cause different page numbering.

Left Page
The left facing page, usually even numbered in left-to-right writing
directions The UA MUST distinguish the left page from the first and right
pages. Typically, when printing documents with a predominately left-to-right
writing direction, this page will be printed on front side of a medium when
printing on only one side of the media and on the back when printing on both
sides. Other binding styles are possible, for example, the standard Japanese
practice is to bind documents on the right rather than on the left, so that
the left and right pages are effectively reversed.

Right Page
The right facing page, usually odd numbered in left-to-right writing
directions. The UA MUST distinguish the right page from the first and left
pages. This is page is printed on the front of a medium for left-to-right
documents. As with the left page, other writing directions and binding
styles will can effectively reverse the left and right pages.

Binding Edge treatment
The binding edge is the page edge that will be stitched, stapled, or punched
with holes when preparing the pages of the document for binding. Graphic
designs of page layouts can call for an increase in the margin of the
binding edge, to accommodate the space needed for binding. Page designs for
documents with a left-to-right writing direction, usually designate the left
side of a page as the binding edge when printing in portrait mode on the
right page. The binding edge is usually on the right side of a portrait
oriented left page when with a left-to-right document that is bound on the
left.. Similarly, The top and bottom edges can be the binding edges when
printing in landscape orientation. There are no provisions within CSS3 for
specifying a binding edge and an accompanying increased margin size.
However, the :left and :right page selectors can be used to write style
sheet rule sets for binding edges.
