That's not the proper definition of &amp;. It's supposed to be

<!ENTITY amp    "&#38;#38;"> <!-- AMPERSAND -->

and that's what all copies of iso-num.ent on my machine say. And that's
*if* you explicitly define it. amp, lt, gt, apos and quot are always
defined, even without a DTD.

As for the "why", the answer would have to be "because XML 1.0 says so".
See http://www.w3.org/TR/REC-xml#sec-entexpand for an example in the
spec itself.
