Usage notes

<clock-value>

This value specifies the length of the simple duration. The value must be greater than 0 and can be expressed with hours (h), minutes (m), seconds (s) or milliseconds (ms). It's possible to combine those time representations to create some complex durations like hh:mm:ss.iii or mm:ss.iii.

media

This value specifies the simple duration as the intrinsic media duration. This is only valid for elements that define media. (For animation elements the attribute will be ignored if media is specified.)

indefinite

This value specifies the simple duration as indefinite.
