Response from the Working Group
================================
Specifications include requirements that cannot be machine checked.
For instance, in the HTML 4.0 specification, the description of the
alt attribute at
http://www.w3.org/TR/html401/struct/objects.html#alternate-text
includes not specifying meaningless alternate text. However, there is
no way for a validator to determine whether the description is
meaningless.

Similarly, the specification for the title attribute at
http://www.w3.org/TR/html401/struct/global.html#title says that the
attribute offers advisory information about the element for which it
is set. There is no way to validate whether the title information is
advisory.
