-//W3C//DTD HTML 4.01 Strict //EN ERROR

how do I get rid of this error

the "grubby" page is

at the w3c validator page

it says
"the Document Type (-//W3C//DTD HTML 4.01 Strict //EN) is not in the
validator's catalog"

I am thinking if (-//W3C//DTD HTML 4.01 Strict //EN is not in their catalog
then why are they suggestion it could be used ?
