trills are encoded in a second layer with note missing @dur. These should be encoded as trills. One might wrap them in a mei:choice though, with mei:orig and mei:reg.

@bwbohl, I'm having trouble determining which trills you're talking about. Can you be more specific please?

I understand these lines to be "explorative" encoding by @KristinaRichts and @MajaHartwig from the early days of MEI. We could put them in a <choice> as @bwbohl suggests, but to me, the proper, metrically correct encoding is not entirely clear to me.

The lazy person that I am I would just delete them.
