The 'ping' element is of an anonymous type so in the generated code
the class is named 'ping' and the parsing/serialization function
names are escaped to 'ping_'. The first line in your code fragment
then should be:

std::auto_ptr<ping> p = ping_(buffer);

You specified the --generate-element-type option which actually
suppresses the generation of parsing/serialization functions and
instead results in element types being generated. For more
information on this, see Chapter 2.9, "Mapping for Global Elements"
in the C++/Tree Mapping User Manual: 

http://codesynthesis.com/projects/xsd/documentation/cxx/tree/manual/#2.9

There is also the 'messaging' example that shows how to use element
types and maps.

If you don't need this functionality and would rather prefer the
parsing functions (so that the above code works), then remove the
--generate-element-* options.
