aloha, laura!

i vastly prefer "incomplete" over "AltNotAsserted" both for brevity's
sake and because an "incomplete" can be used to signify missing @alt
as well as missing @src, which is also "incomplete"

why use a predefined attribute value rather than a dedicated attribute?

1. it is simpler

2. it applies equally to the 2 components of an IMG that make an IMG
usable: @src and @alt

3. it is highly unlikely that the value "incomplete" will be used as
an @alt text value

EXAMPLE A. auto-inserted "incomplete" value for @alt:

<img src="foo.png">

transforms to 

<img src="foo.png" alt="incomplete">

EXAMPLE B: auto-inserted "incomplete value for @src

<img alt="Victoria standing in front of the Eiffel Tower">

transforms to:

<img src="incomplete" alt="Victoria standing in front of the Eiffel Tower">

this reinforces the equal priority of @alt and @src to conforming 
HTML, gregory.

 Missing is a little ambiguous as to what is actually missing.
