Please provide an example of why you think this is a bug.

This would be wrong. XML entity substitution is recursive, so the above
would cause `AT&T;' to expand to `AT&T;', and then further
substitution would fail since there is no entity `&T;' defined.
The way it is set up now, `AT&T;' expands to `AT&T;', which
finally gives the literal text `AT&T;'.
