Which is just one of the resources I drew upon (and linked) in my
article on the matter:

Principles of XML design: When to use elementsversus attributes

Which, over all, I think is broader and covers more of the "list of
differences" Rick mentions.

BTW, "if you need order use elements and if not, use attributes" is far
too simplistic.  What about making the choice when there's only one data
element to model?  What about consideration of internal structure in the
data item that might trump the order issue (we don't get all our data
tediously normalized).  Again, I dig more deeply in the article.
