Attribute for `<IFRAME ...>`
`LONGDESC`

Similar to <IMG LONGDESC="...">, W³C describes LONGDESC as "a link to a long description of the frame". Like <IMG LONGDESC="...">, we don't know of any browsers that actually support this attribute, but it would be a worthwhile thing to support. Copyright 1997-2002 Idocs Inc.
