how to view makeinfo-generated xml?

[Charlie Zender]

Hi,

I've generated XML using makeinfo two different ways
on a TeXInfo file for a project called NCO:
 
makeinfo --xml --output=nco.xml nco.texi
makeinfo --docbook nco.texi

My question is: How do I view the resulting nco.xml files?
I tried loading them into mozilla (1.1) to no avail.
Mozilla complains:

XML Parsing Error: undefined entity
Location: file:///home/zender/nco/doc/nco.xml
Line Number 10, Column 11:Copyright &copyright; 1995-2002 Charlie
Zender
----------^

for the former --xml version and, on loading the --docbook version, complains

XML Parsing Error: syntax error
Location: file:///home/zender/nco/doc/nco.xml
Line Number 1, Column 55:<!DOCTYPE Book PUBLIC "-//OASIS//DTD DocBook V3.1//EN">
------------------------------------------------------^

So is the problem with nco.texi, makeinfo, mozilla, or me?

Thanks,
Charlie
