Provide @perf on actor

[lb42]

The attribute @perf (performance) is available on elements <move> and <tech>; in the former case it "identifies the performance or performances in which this movement occurred as specified by pointing to one or more performance elements"; in the latter it "points to one or more performance elements documenting the performance or performances to which this technical direction applies". As discussed recently on TEI-L, if this were also available on the <actor> element, it would be possible to associate an actor's name with a specific performance. This would greatly simplify the encoding of <castList>a presenting details of multiple performances. Such an extension clearly retains the semantics of the existing attributer and meets a clearly defined need.

I leave it to Council to decide whether this should be met by defining the attribute afresh on the <actor> element, or by defining a new attribute class att,performed vel sim, with members actor, move, and tech. The former would be quicker and easier; the latter more elegant.

Agreed. And I personally think this should be an attribute class with the membership that @lb42 suggests plus all members of model.stageLike.

One question that arose in the discussion— and perhaps this is another ticket — is whether @perf must point to performance elements or if it could also point to an event (in the case where a performance is not explicitly documented in the text itself or if there are details of the performance omitted in the text but captured in a standoff event). I see no harm in loosening that constraint.

Council subgroup at F2F 2025 agrees that @perf should be available on all members of model.stageLike, actor, as well as castList, castItem, and role and that it should be able to point to any kind of event (usually event or performance element(s))
