Hi Peter,

I agree with what Adam said. This code says "translate anything
starting with & to &, except &a, &m or &p, which should be left alone".
So what will you do if someone passes another character entity besides
&? Suppose they send you < for example, you'll wind up with
&lt; which is wrong. You don't really want to translate & only when
it's not & (which is what you seem to think). What you really want
to do is translate & when it's not part of a character entity -- which
is extremely hard to do!
Well-formed XML escapes the & character for a good reason. Whomever is
coding XML with unescaped & characters needs to be stopped. No XML
reader should accept XML that's not well-formed.
