Layering. There is already far too much interaction between the physical
and logical layers of XML, e.g. the rule that tags in an external entity
must be well-balanced. It would ideally be possible to do all the
lexical processing without any interaction with the syntax processing.
The fact that namespaces are not even part of the XML syntax, but a
semantic layer on top, would compound the problem even further.

<a xmlns:foo="&foo:entity"/>
