Authors are urged to provide alternate methods of accessing files
referenced by the SOUND element if they are important to the content of
the page (perhaps by using a hyperlink) due to support only in Mosaic.
DTD NOTE: This element does not exist in
any official references, so I decided to model it after the BGSOUND
element used by Internet Explorer, which it VERY closely resembles.
Recommendation: Do NOT use this element, since
it was only supported by Mosaic - a browser that is no longer being made.
