Description

The valuetype provides a mechanism for defining exactly what type of data is being passed to the parent object. If no valuetype is specified, the user agent assumes the default value of "data". You only really need to bring the valuetype attribute in to play if the content inside the value is a URL pointing to a file with the necessary information contained (in the example above, the reference is to a text file poly.txt which would, presumably, contain the set of rules or co-ordinates required to draw a polygon shape), for which you’d specify a valuetype of "ref". If "object" is specified as the valuetype, the value attribute should correlate to another object on the page, referenced by that object’s id:

<param name="handler" value="mplayer" valuetype="object"/>
…
<object id="mplayer">
…
</object>
