I dont understand the char_type member typedef of the traits class. The
functions that use it all seeem to be free functions which could change from
void read_xml(std::basic_istream<typename Ptree::char_type> &stream,
int flags = 0);
template<class Ptree, class Char>
void read_xml(std::basic_istream<Char> &stream, Ptree &pt,int flags = 0);
without problems. That would remove one level of coupling wouldnt it?
Why are all ptree nodes the same type? Commonly a tree will have branch and leaf
nodes. In the debug example there are two branch nodes and 4 leaf nodes, which
means two empty lists . That is wasteful isnt it?
Is it necessary to make key a string. Could it not also be (say) an integer id?
