The first design uses a “hardcoded approach to XML design.” The <graduation> element hardcodes the event.

In the generic approach the semantics is in the attribute value. In the hardcoded approach the semantics is in the element name.

They are both hardcoded: in one case the element name is hardcoded, in the other, the attribute name is hardcoded. In fact, element names ("general identifiers" in SGML-speak) are simply the values of an attribute that has no name.

GMail doesn't have rotating .sigs, but you can see mine at http://www.ccil.org/~cowan/signatures
