Apple Pages: Use a different header for odd an even pages
This is currently not possible with Pages, as it was with Pages '09.

If you need this functionality, you can still use Pages '09 if you have it, but opening a document from Pages '09 with different headers for odd and even pages will cause such headers to be removed (and a warning thrown in Document Warnings).
