Document how polling should work.

parent 19c08363
When a link (but not form or form input) has a `prepend`, `append`, or `replace` attribute in addition to a `poll` attribute, that poll attribute should be parsed as a CSS time unit and lead the user agent to subtly confirm the action with the user. Given that permission it should procede to send a request out at the frequency but only after the previous one has closed, with the response handled as per it's other attributes.
If the response has a `Snippet-Poll` HTTP header and the value is a number of milliseconds greater than the frequency confirmed by the user, the polling frequency should be adjusted. If it's 0 then the polling should stop.
