Sure, which is what you use stylesheets for. If you don't have
stylesheets, use attributes. Do you call a file in you file system
foo-1023-bytes-created-on-march-fifth-1993

additional information related to foo? The same thing applies to
tag names. Also, as people have said time and time again, presentation
depends very much on the presentation media: what does <BLINK> mean to
a speech-synthesis unit?
