 * ospxmltype.h - Structures and prototypes for generic XML character
 *                types. These are more or less a duplication of the
 *                ANSI ctype.h functions. It is necessary to write
 *                them from scratch, though, in order to ensure
 *                strict XML compliance.
 *
 *                Note that the implementation treats each XML character
 *                as a C char, which is mostly likely 8 bits. The XML
 *                decoding routines still accept 16-bit characters
 *                though. Since the OSP uses only ASCII characters,
 *                any 16-bit encoding can be safely converted to 8-bit
 *                char variables.
