Re: Default alt attribute for site-logo in a CMS

The alt attribute should present the content of the image. It seems
this would generally be at least the site-name. If the logo also
presents the site-slogan, then it should be site-name + site-slogan.
If you went with site-name + site-slogan, and site-slogan wasn't
defined, it would just present site-name, correct? If so, then this
would probably be the best default - unless the site-slogan is
typically presented in text separate from the logo, in which case this
would be repetitive and just site-name would be best.

This highlights the difficulty in specifying an accessibility default
for content that is user-specified.

You are correct that "Home" would almost never be appropriate. Having
the site name be the alternative text would be very important for SEO.
A link at the top of the page that presents the site name is a very
common convention - it's not necessary to inform a screen reader user
that it's a link to the home page as this is quite obvious (just as it
is obvious that sighted users can click a linked logo to go to the
home page).
