///////////////////////////////////////////////////////////////////////////////
//
// Dump a parse tree as a xml stream
//
// The functions 'tree_to_xml' can be used to output a parse tree as a xml
// stream into the given ostream. The parameters have the following
// meaning:
//
// mandatory parameters:
// ostrm The output stream used for streaming the parse tree.
// tree The parse tree to output.
//
// optional parameters:
// input_line The input line from which the parse tree was
// generated (if given, it is used to output a comment
// containing this line).
// id_to_name A map, which is used for converting the rule id's contained
// in the parse tree to readable strings. Here a auxiliary
// associative container can be used, which maps a rule_id to
// a std::string (i.e. a std::map<rule_id, std::string>).
// get_token_id
// A function or functor, which takes an instance of a token
// and which should return a token id (i.e. something like
// 'int f(char const c)').
// get_token_value
// A function or functor, which takes an instance of a token
// and which should return a readable representation of this
// token (i.e. something like 'std::string f(char const c)').
//
// The structure of the generated xml stream conforms to the DTD given in the
// file 'parsetree.dtd'. This file is located in the spirit/tree directory.
