A document with an image that represents a map of the Mediterranean in 180 AD. The document contains an object element that embeds the map in GIF format; inside the object element is an img element that embeds the same map in JPEG format. The img element has an alt attribute, a title attribute and a longdesc attribute. The alt attribute identifies the image but the image is too complex to be described in an attribute. The longdesc attribute refers to a section inside the same page that identifies the image and conveys the same information. Long description for complex image: image inside object; longdesc on image refers to section below object Christophe.Strobbe@esat.kuleuven.be en Copyright BenToWeb 2005-2007 2005-08-30 validated General Inclusion: The object element How to specify alternate text The longdesc attribute

This test case is intended to pass because the alt attribute provides a short description and the longdesc attribute points to a section (below the image) that contains an appropriate text alternative. The test is for the longdesc attribute rather than the alt attribute. Strictly speaking, this should work, but poor support for longdesc and the object element in some browsers may cause problems.
