Thanks Lou!

You are correct. The changes I made from the original were:

    * the svg:svg is replaced with a tei:pg (the physical page),
    * each svg:view is replaced with a tei:area (a rectangular region of the page),
    * the svg:image is replaced with a tei:graphic (an image of the page)

    * the svg:rect elements are ignored (I'd argue they should be the responsibility of presentational stylesheets rather than in the base encoding),
    * the markup of the English and Latin text has not changed,
    * neither has the linkGrp which aligns the English and Latin text and the areas of the image.

I have a version of it with more text. At present it's not in a state that's acceptable to Roma, but I'm working on it. I'm sorry about that ... I will post something shortly though.

I envisaged it as an entirely separate module, though it clearly depends on FT (for graphics). I think it is a separate concern entirely from encoding figures and so on, and there'd often be situations where tei:graphic was needed without the facsimile markup.

and

Not really, the pb element is still empty (I think! unless Dot changed that :-) and is merely linked to the <pg> element by reference. The pg element contains only graphics and areas, not text. The bits of text are linked to the area elements by reference. It is a kind of (graphical) stand-off markup, with respect to the text.
