Status: accepted

Change Description: rationale added to spec

Rationale: 

An image contains relevant information, an alternative interpretation of which
is available in the same document as structured text. Using an empy alt
attribute hides an image from some users, which is incorrect, the image is not
meaningless, it contains information which a range of users could interpret
with the aid of the short text alternative and longer description. It also
provides a text alternative for users who have images turned off in their
browsers, so they can if they wish load and view the image. If an empty alt
attribibute is present there may be no indication that an image is present.
Also if a description of an image is provided in a document, a programmatic
association between the image and the descriptive text is required, using an
empty alt attribute on the image effectively precludes the assigning of a
programmatic association.
