The XmlData class encapsulates a buffer for storing and retrieving binary data (uninterpreted bytes). The default and copy constructors for XmlData manage their own memory and the application need not be aware of it. The constructors, XmlData(const Dbt &dbt) and XmlData(void *data, size_t size), create "wrapper" objects for the memory passed in and in those instances it is up to the application to own and manage the memory. If a wrapper object is assigned data that is larger than its memory buffer an exception will be thrown.
