Because attributes are conventionally used to hold metadata, as opposed
to data; that is, they express properties of an element.  For instance,
if one were to state that they would like a car that is "red, 2-door,
and 6 cylinder" (without implying priority), they could just as well say
"2-door, 6 cylinder, and red" and not sacrifice the meaning.
