The specification explicitely states that ALL character data is to be 
passed on to the application, see 
http://www.w3.org/TR/xml/#sec-white-space . Most of the small XML parser 
libraries out there like TinyXml, PugXML, PugiXML, RapidXML and so on 
are completely broken in this respect. There is no meaningful way to 
differentiate between whitespace that is to be ignored and whitespace 
which is not, see
