AR finished REME2 CSS, so I went through and cleaned up a bit, moving some definitions to rendition elements, clearing up some tagging confusion, and moving some labels around a bit. In the process, I added the option to provide explicit style on page-break hrs by adding a rendition element in the header with xml:id="[FILEID]_pb". This will be very handy for Stow. Waiting on some metadata and proofing before we can publish.
