"&" in a url is correct when the url is the value of an attribute.
Most html browsers however tolerate a plain "&" there, even though it is
not correct (since it is a common mistake).
However, "&" is not correct when the url is actually used to find a
network address. The browser takes care of converting the entity to the
actual character value (which in this case is "&"). So your server
should not be seeing any "&" entities in requests.
So there should not be any need to escape the "&" in your output,
but perhaps you are doing something that would better be done in some
other way. Could you explain more about the problem you say your server
is encountering?

See, you cannot have a bare "&" in the xml or html anywhere, whether in
the source, the stylesheet, or the output (unless it is text output).
Internally, the processor stores "&" in place of "&", so all the
strings are stored as intended and it is just a matter of getting the
output you intend to get.
