Just for the record, the alt attribute on the img element was NOT
required in HTML 3.2, (never-standardized) HTML 3.0 and HTML 2.0.
Same for HTML i18n (RFC 2070).  It was changed in HTML 4.0.

Of course it is required in ISO-HTML.

Note that the alt attribute on the area element was not required in
RFC 1980, but it is required in HTML 3.2 and later.
