Canonical XML comment (example 3.6)

Hi John,

In example 3.6 (UTF-8 Encoding) you forgot to include the 
required version info into the XML declaration. So the input
document should be 

<?xml version="1.0" encoding="ISO-8859-1"?>
<doc>&#169;</doc> 

instead of

<?xml encoding="ISO-8859-1"?>
<doc>&#169;</doc> 

Regards, Gregor
