After the team mtg, met with MH, TEH, and JJ and came up with a plan for encoding the QME performances. Since performances must be understood as equal to the text (and textual artifacts), we are encoding the performances using a `<facsimile>` element, with `<surface>`s representing individual scenes; these surfaces will then be keyed to a timeline, at which divs can point using `@corresp`.

I'm going to test out this method with FV and report back.
