(a) I agree people write stuff this way, and (b) I agree
it's just plain wrong, so (c) I think it's critical that
this issue (things versus their names, numbers vs. numerals...)
is treated by the primer.

Case in point: folks write
	<dc:creator>Dan Connolly</dc:creator>
as if a character sequence "D" "a" "n" ... wrote a book.
It's critical that we teach folks to write
	    <fullName>Dan Connolly</fullName>

or, more briefly:
	<dc:creator contact:fullName="Dan Connolly"/>
