Page and Sheet Numbering
Page breaks are captured in accordance with the DTABf guidelines for tagging page numbers as follows:
<pb facs="#f[image number]" n="[page number]"/>
Even if the manuscript is not paginated itself, the <pb>
element that contains the facsimile number in the @facs
attribute is always present.
If the manuscript is also foliated, the folio number is reproduced in the <fw>
element, which contains the @type="folNum"
attribute value pair.
<fw type="folNum">[sheet number]</fw>
