However, you can get leading whitespace if the XML decl is not present 
(http://www.w3.org/TR/REC-xml/#NT-prolog).  Or you might get the start of an 
element, doctype decl, PI or Comment (and maybe some other things!).  That 
results in the 'Other' case at 
http://www.w3.org/TR/REC-xml/#sec-guessing-no-ext-info.

Cheers,

Pete.
