For arts organizations, it's more to do with transparency and explaining and showing where we are, rather than a top-down, legislated, or rules-based requirement. It allows the patrons and the audiences to see how many women are involved and at what level. I think it's more on a reporting side and explaining to the public where women are involved.
Certainly, in the performing arts industry, there's a very strong movement afoot; the public themselves are sort of forcing that issue.
