25 * User Documentation for Xerces Version Values:
26 *
27 *
28 *
29 * Xerces  Notes:
30 *
31 * Xerces Committers Documentation:
32 *
33 *    Xerces committers normally only need to modify one or two of the
34 *    following macros:
35 *
36 *      XERCES_VERSION_MAJOR
37 *      XERCES_VERSION_MINOR
38 *      XERCES_VERSION_REVISION
39 *
40 *    The integer values of these macros define the Xerces version number. All
41 *    other constants and preprocessor macros are automatically generated from
42 *    these three definitions.
43 *
44 *    The macro XERCES_GRAMMAR_SERIALIZATION_LEVEL has been added so that during
45 *    development if users are using the latest code they can use the grammar
46 *    serialization/desialization features.  Whenever a change is made to the
47 *    serialization code this macro should be incremented.
48 *
49 * Xerces User Documentation:
50 *
51 *  The following sections in the user documentation have examples based upon
52 *  the following three version input values:
53 *
54 *    #define XERCES_VERSION_MAJOR 19
55 *    #define XERCES_VERSION_MINOR 3
56 *    #define XERCES_VERSION_REVISION 74
57 *
58 *  The minor and revision (patch level) numbers have two digits of resolution
59 *  which means that '3' becomes '03' in this example. This policy guarantees
60 *  that when using preprocessor macros, version 19.3.74 will be greater than
61 *  version 1.94.74 since the first will expand to 190374 and the second to
62 *  19474.
63 *
64 *  Preprocessor Macros:
65 *
66 *    _XERCES_VERSION defines the primary preprocessor macro that users will
67 *    introduce into their code to perform conditional compilation where the
68 *    version of Xerces is detected in order to enable or disable version
69 *    specific capabilities. The value of _XERCES_VERSION for the above example
70 *    will be 190374. To use it a user would perform an operation such as the
71 *    following:
72 *
73 *      #if _XERCES_VERSION >= 190374
74 *        // code specific to new version of Xerces...
75 *      #else
76 *        // old code here...
77 *      #endif
78 *
79 *    XERCES_FULLVERSIONSTR is a preprocessor macro that expands to a string
80 *    constant whose value, for the above example, will be "19_3_74".
81 *
82 *    XERCES_FULLVERSIONDOT is a preprocessor macro that expands to a string
83 *    constant whose value, for the above example, will be "19.3.74".
84 *
85 *    XERCES_VERSIONSTR is a preprocessor macro that expands to a string
86 *    constant whose value, for the above example, will be "19_3". This
87 *    particular macro is very dangerous if it were to be used for comparing
88 *    version numbers since ordering will not be guaranteed.
89 *
90 *    Xerces_DLLVersionStr is a preprocessor macro that expands to a string
91 *    constant whose value, for the above example, will be "19_3_74". This
92 *    macro is provided for backwards compatibility to pre-1.7 versions of
93 *    Xerces.
94 *
95 *  String Constants:
96 *
97 *    gXercesVersionStr is a global string constant whose value corresponds to
98 *    the value "19_3" for the above example.
99 *
100 *    gXercesFullVersionStr is a global string constant whose value corresponds
101 *    to the value "19_3_74" for the above example.
102 *
103 *  Numeric Constants:
104 *
105 *    gXercesMajVersion is a global integer constant whose value corresponds to
106 *    the major version number. For the above example its value will be 19.
107 *
108 *    gXercesMinVersion is a global integer constant whose value corresponds to
109 *    the minor version number. For the above example its value will be 3.
110 *
111 *    gXercesRevision is a global integer constant whose value corresponds to
112 *    the revision (patch) version number. For the above example its value will
113 *    be 74.
