        Description copied from interface: ParamParent
        Adds a parameter to this tag's URL. The intent is that the <param> subtag will call this to register URL parameters. Assumes that 'name' and 'value' are appropriately encoded and do not contain any meaningful metacharacters; in order words, escaping is the responsibility of the caller.
