Personal taste. This is a religious issue. Attributes differ in
that
- 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
