Always true.

The HtmlTextWriter class implementation of the IsValidFormAttribute method returns true for all attributes. Override the IsValidFormAttribute to limit the attributes that can be rendered in the opening tag of a <form> element.

Notes to Inheritors: Override the IsValidFormAttribute method to return true only for those attributes that can be included in the <form> element of the markup for which the class derived from the HtmlTextWriter class is intended.
