I *strongly* disagree with this opinion. If the only method to 
"understand" the meaning of an HTML (or XML) tag is to check the doc 
type, we are in deep trouble. Many tools never will see the doc type 
(such as XSLT), and the association will be broken as soon as document 
fragments are copied into other documents.
