Personal taste.  This is a religious issue.  Attributes differ in 
- they get white-space-normalized
- their order is not significant
- you can't have more than 1 with the same name on an element
- they can't contain any internal structure

If these things matter, your decision is made.  If not, make it yourself.
Lesson: software writers have to be able/willing to pull information
out of either elements or attributes. -Tim
