  The documentation doesn't say it is, so assume it's an
implementation detail.  The right way to test this is to use the
result as a boolean, not to compare it to a specific value:

    if (XML_ParseBuffer(...)) {
        /* handle the error */
        ...
    }
    else {
        /* do useful work */
        ...
    }
