didOpen notification

[cdietrich]

Hi, where and how does langium handle didOpen notification?
is it possible to have a set of completely transient documents?

@cdietrich We handle neither didOpen nor didClose events/notifications explicitly. We only react to the didChange event of the text documents. Note that the event is also fired when a file is opened in the editor.

is it possible to have a set of completely transient documents?

I.e. documents that only live in a service instance for a short duration and are then deleted? We use something often in interpreters, see here for example.
