Think of it this way:
- you're using the validator because you want to conform to a standard
- the above mentioned standard (XHTML 1.0) says "all images must have 
alt tags"

So basically, if you *want* your XHTML to be valid you *want* alt tags 
for all images.


And yes, we could go the other way around and argue over whether 
"layout images" as you call them are useful or harmful, but please, no, 
that's off-topic on the validator's list.

Hope this helps.
