If you want to defend yourself against unreliability in the transport layer
and below, you could (a) use a more reliable transport layer, or (b) add a
checksum or signature.
XML has plenty of redundancy and this does have the virtue that many file
corruptions will be detected automatically. But I don't think that argument
is strong enough to justify this inconvenience. Besides, you could apply it
just as much to external entities, which don't currently have this
restriction (and I don't see the world catching fire because external
entities are being corrupted all over the place).
