Paged Media Level 4

Some ideas for features for a future Paged Media Level 4 spec:

• 'allow' value for page-break properties (preferred vs acceptable breaks)
• :blank page selector
• some of what's currently in GCPM
• top-of-page margin collapsing control
• ability to control total pages counter
• ability to repeat table captions, change text slightly (add '(cont.)', etc)
• ability to wrap rows
• ability to apply widows/orphans pagination controls to table rows in a table (vs lines in a paragraph)
• add percentage to page-break-before(after) as conditional page break. (See http://lists.w3.org/Archives/Public/www-style/2009Apr/0039.html)
• :front and :back page selectors (like :left and :right, but determined by writing order)
• @margin-box selector to set values common to all margin boxes
