I was pondering https://twitter.com/TEI_Pelican/status/1436279338182189056 in which it's claimed that the tag <ellipsis> doesn't feature in any TEI documents in the wild so far dredged up by the pelican, when one of the students in this year's TEI course in Tours asked how to deal with a manuscript like the attached:  its a play script showing just one actor's part, the horizontal lines representing other actors' speeches. A real life case for <ellipsis> I think.
