You can use std::ostringstream to serialize the diagnostics to a string.
You can also programmatically access each parsing/serialization diagnostics
message by catching the xml_schema::parsing and/or xml_schema::validation
exceptions and using their accessors to extract this information. For
details, see Section 3.3, "Error Handling" in the C++/Tree Mapping User 
Manual:
