XML could have achieved far better separation if it had chosen. The intertwingling of the physical and logical layers caused by the rule that elements must be well-balanced within entities is a quite unnecessary constraint on implementation modularity; the interactions between entity expansion and syntactic parsing within DTDs are even worse. I don't think it's at all true that these complications are inevitable.
