# WebPlugInAttributesKey

The `NSDictionary` object containing all names and values of all attributes of the plug-in’s associated HTML element, as well as all names and values of the parameters to be passed to the plug-in. For example, this dictionary will contain all `PARAM` elements within an `APPLET` element. If attribute and parameter names conflict, the attributes of an element take precedence over any of its parameters. All keys and values in this dictionary must be of type `NSString`. *Required key*.
