			== Intended Use ==
			Clients supporting [[hCaptcha]], (say for example, Firefox) could present end-users with a configuration option for the types of captcha they wish to use.

			* If the client is configured for "audio only" captchas, the client would either only present (read "modify DOM") captchas identified as being audio captchas, or not download non-audio captchas (e.g. img or object data that isn't audio).
			* If the client is configured for "visual only" captchas, the client would either only present (read "modify DOM") captchas identified as being visual captchas (img or object data such as flash/quicktime etc), or not download non-visual captchas.
			* If the client is configured for "text only" captchas, the client would only display text-based captchas such as simple math questions, riddles etc.
			* If no preferred captcha is available, "fair-use" software could be employed to reverse engineer the available captchas into preferred formats.
			* [http://labs.google.com/accessible/ Google's "Accesible Search"] could use hCaptcha to help weight the results of pages using captchas.

			== Assessment of nefarious use of hCaptcha ==
			While hCaptcha would make it easier for spammers to identify captchas in a page, it could also be used in a similar manner to Firefox's "AdBlock" extension- e.g. providing humans without ulterior motives a means of automatically filling in a captcha response.
			Either way, the result of a de-captcha program wouldn't be affected by the implementation of hCaptcha.

New page

== Draft Specification ==
=== Editor/Author ===
:[[User:SignpostMarv|SignpostMarv]]

=== Implicit markup ===
The class value '''captcha''' applied to any non-data submission element implies that this element contains captcha content (e.g. a, img, object).

The class value '''captcha''' applied to a data-submission element implies that this element is for indicating the captcha response (e.g. input, textarea, select)
