param Element

 

Module

The param element is declared by the XHTML 1.1 Object Module (Param)

Elements in the Object Module are:
object
param (Param Support Module)

Description

A param element is used to specify a run-time initialisation parameter for an object.

Although not explicitly required by the XHTML 1.1 DTD, a comment within the DTD states that param elements should be placed prior to other content in the object element (ref: *Embedded Object Module DTD at the W3C).

I don't use object much so I'll just refer you to the W3C's Specification for *HTML 4.01 - Object initialization: the PARAM element (which has the same function as this corresponding XHTML element).

The name attribute is #REQUIRED on the param element.
