This is a libxml2 schema validation error that the PHP DOM extension
is just passing along. When such an error occurs, the schemaValidate()
method should return false.

What I believe the error is trying to express is that your XML Schema
has declared the comment element to be of the basic (as compared to
complex) type "date," but your document contains a different type of
element. Hence it "failed to validate basic type date."

I agree that this isn't the most informative of error messages, but as
I said, this is what libxml2 generates. If we want to fix it, we need
to fix the libxml2 sources, which is actually easier done than I'm
making it out do be, but is harder than just making a change to the
PHP DOM extension.

Make sense?
