Setting a default of alt="" is bad behaviour, since the program has no way of 
knowing what an appropriate alt might be (the behaviour described with user 
interaction is ideal), and makes an arbitrary decision that makes it more or 
less impossible to flag the problem and repair it later.

The application should simply leave out the alt attribute. This makes it 
trivially easy to build a repair application where one is required or desired, 
and has no practical drawback if the error is left in (given the state of HTML 
email standardisation...).

This should be lear from the W3C's authoring tool accessibility guidelines - 
http://www.w3.org/TR/ATAG which were desgined with a variety of tools in mind 
including CMS and email.
