I obviously disagree but was wondering if there is a record of this 
"deliberate, careful design decision" in canonical or non-canonical 
documentation about the drafting of XML? (If enforced nesting of 
elements is not a defacto data model I am not sure what definition is 
being used for data model. Not using the words "data model" does not 
make it any less a data model.)
