A DTD tells you "these are the elements and attributes that may appear
in a document, and the order and combinations in which they may
appear." If a document doesn't match those specifications, for any reason
whatever, it is invalid.
For information about stylesheets, CSS, parsers, and XML in general, I
would recommend that you buy the book "Learning XML" by Erik Ray,
published by O'Reilly. It's a good introduction, and the examples are
actually fun to read.
