/**
 * User Documentation for Xerces Version Values:
 *
 *
 *
 * Xerces  Notes:
 *
 * Xerces Committers Documentation:
 *
 *    Xerces committers normally only need to modify one or two of the
 *    following macros:
 *
 *      XERCES_VERSION_MAJOR
 *      XERCES_VERSION_MINOR
 *      XERCES_VERSION_REVISION
 *
 *    The integer values of these macros define the Xerces version number. All
 *    other constants and preprocessor macros are automatically generated from
 *    these three definitions.
 *
 *    The macro XERCES_GRAMMAR_SERIALIZATION_LEVEL has been added so that during
 *    development if users are using the latest code they can use the grammar
 *    serialization/deserialization features.  Whenever a change is made to the
 *    serialization code this macro should be incremented.
 *
 * Xerces User Documentation:
 *
 *  The following sections in the user documentation have examples based upon
 *  the following three version input values:
 *
 *    #define XERCES_VERSION_MAJOR 19
 *    #define XERCES_VERSION_MINOR 3
 *    #define XERCES_VERSION_REVISION 74
 *
 *  The minor and revision (patch level) numbers have two digits of resolution
 *  which means that '3' becomes '03' in this example. This policy guarantees
 *  that when using preprocessor macros, version 19.3.74 will be greater than
 *  version 1.94.74 since the first will expand to 190374 and the second to
 *  19474.
 *
 *  Preprocessor Macros:
 *
 *    _XERCES_VERSION defines the primary preprocessor macro that users will
 *    introduce into their code to perform conditional compilation where the
 *    version of Xerces is detected in order to enable or disable version
 *    specific capabilities. The value of _XERCES_VERSION for the above example
 *    will be 190374. To use it a user would perform an operation such as the
 *    following:
 *
 *      #if _XERCES_VERSION >= 190374
 *        // code specific to new version of Xerces...
 *      #else
 *        // old code here...
 *      #endif
 *
 *    XERCES_FULLVERSIONSTR is a preprocessor macro that expands to a string
 *    constant whose value, for the above example, will be "19_3_74".
 *
 *    XERCES_FULLVERSIONDOT is a preprocessor macro that expands to a string
 *    constant whose value, for the above example, will be "19.3.74".
 *
 *    XERCES_VERSIONSTR is a preprocessor macro that expands to a string
 *    constant whose value, for the above example, will be "19_3". This
 *    particular macro is very dangerous if it were to be used for comparing
 *    version numbers since ordering will not be guaranteed.
 *
 *    Xerces_DLLVersionStr is a preprocessor macro that expands to a string
 *    constant whose value, for the above example, will be "19_3_74". This
 *    macro is provided for backwards compatibility to pre-1.7 versions of
 *    Xerces.
 *
 *  String Constants:
 *
 *    gXercesVersionStr is a global string constant whose value corresponds to
 *    the value "19_3" for the above example.
 *
 *    gXercesFullVersionStr is a global string constant whose value corresponds
 *    to the value "19_3_74" for the above example.
 *
 *  Numeric Constants:
 *
 *    gXercesMajVersion is a global integer constant whose value corresponds to
 *    the major version number. For the above example its value will be 19.
 *
 *    gXercesMinVersion is a global integer constant whose value corresponds to
 *    the minor version number. For the above example its value will be 3.
 *
 *    gXercesRevision is a global integer constant whose value corresponds to
 *    the revision (patch) version number. For the above example its value will
 *    be 74.
