RE: Glossary "non-text content" Small Nit

I think this thread began as a discussion about how to define non-text
content for the purposes of WCAG 2.0. I think there was an unspoken
assumption that the problem has to do with non-text content as it is
rendered for users, rather than with the form in which such content is
transmitted.

Does that distinction make sense? Can we focus on a glossary definition
that will help developers and other readers of WCAG 2.0 understand when
something qualifies as non-text content (and is thus within the scope of
Guideline 1.1)?

Thanks,
John

In MIME, yes. But this is Web Content Accessibility, not Email 
Accessibility. However, there may be situations when binary data are 
stored as characters, Base64 encoded, e.g. when using the data URL
scheme.
