> Hi.
> This is just a question for clarification on the functionality of action
> GATHER. As far as I can tell, it creates a new annotation of the given type,
> spanning the matched annotation of the given rule elements and allows to
> assign them to the features of the created annotation.
> But how is this different from the CREATE action? I'd argue that the latter
> can do the same and more, which would render GATHER irrelevant. Just by using
> LabelExpressions instead of NumberExpressions as arguments:
> {noformat}
> A B{-> GATHER(C, 1, 2, "a" = 1, "b" = 2)};
> // VS
> x:A y:B{-> CREATE(C, 1, 2, "a" = x, "b" = y)};{noformat}
> Some clarification would be great. Thank you.
> Best, Michael
