An equivalent attribute sounds like a good idea. What data type would
it accept? For something like a CAPTCHA, where there could be more
than one alternative, it would need to be able to accept more than one
value, with those options being exposed by the user agent.

Could this also be implemented using content negotiation? People could
configure their user agents to suggest the challenge most suitable for
them, and the service could check the accept headers to choose the
most appropriate version, and the author provides the option to allow
the user to change the challenge at any time.
