The infoset implies a tree structure because XML implies a tree

"""Exactly one of the element information items corresponds to the 
document element (the root of the element tree), and all other 
element information items are contained within the document element, 
either directly or indirectly."""

What the infoset does NOT DO is require implementations to directly
expose that tree structure. The DOM is a particular API which should be
based on the information set. It happens to be tree strucuted so it
directly exposes the tree

Egad. Heaven help us when the DOM and XPath start telling us what to
read into XML 1.0! It is, after all, much more widely implemented and
documented and is not, in my personal opinion "out of date" at all.

What does XML say that is different?

So you are arguing against logical and terminlogical consistency??

It wouldn't help...there are lots of other problems. The handling of
text in the DOM and XPath is a particular nightmare.
