Subject: [PATCH] add fallback for blank $movID

Although the stylesheet was designed in a context that always required
a mdiv element to have a xml:id, it also was in a context where only
one mdiv was being processed at a time.
This commit introduces a fallback to fn:generate-id() if $movID is blank
