Remarks
The members listed in the preceding table might not be accessible through scripting until the window.onload event fires. waiting for this event to fire ensures that the page is completely loaded, that all behaviors have been applied to corresponding elements on the page, and that all the behavior's properties, methods, and events are available for scripting. using any of the behavior-defined members before the window.onload event fires could result in a scripting error, indicating that the object does not support that particular member.
although different media-based elements exist, there is no functional difference in their current implementation. however, you are encouraged to use elements such as t:audio, t:img, t:media, and t:video for improved document readability and enhanced support.
the prefix t is used to associate this element with an xml namespace. you must include the following line of code in the head section of your html document when using this element.
<xml:namespace prefix="t"/>the t:media element is available as of microsoft internet explorer 5, only in the microsoft?win32?platform.
