hi maciej,

> For example, here is an excerpt of raw source for an email produced by
GMail, notice lack of alt on the img elements:

i checked the code of this email (gmail) using the validator.nu as its
marked up as HTML5 (well it uses the HTML5 doctype)

If we are basing conformance rules solely on what a particular email client
or authoring tool is likely support, then there are a lot of other
exceptions we should make for email clients and authoring tools.

here are the results from validator.nu:
