Is there any logical or technical reason (with the W3C validation) for making alt as required attribute ..

This is my actual problem:

though my page is perfect enough with respect to W3C validation rules .. Only error I am getting is

line XX column YY - Error: required attribute "ALT" not specified

I know the significance of "alt" attribute and I have omitted that where it is unnecessary .. (to be more elaborate .. I have added the image to increase the beauty of my page and I don't want alt attribute to show irrelevant message to the viewer)

getting rid of the error is secondary .. rather I am curious to know whether is it a flaw with validation rules .. ??

I thank stackOverflow and all the members who responded me .. I got my doubt clarified .. :-)
