I'm asking why do they have no inherent order. "Because the implementation
might be some wacky hash table" is a circular argument. But you did almost
satisfy my curiosity with this point:

It still seems a bit arbitrary that certain types of nodes simply don't
have an inherent order. If order can be imposed on elements, text,
comments and processing-instructions...

Touché!

Agreed. See my reply to Michael Kay for more on this.
