This appendix describes all of the status codes that may be returned during program execution in two sections. Runtime error messages are divided into two sections: the first for general errors that are not specifically related to XML, like socket read errors or end of buffer messages, and the second for errors related specifically to XML, mismatched tags.

The runtime error messages may be found in the runtime documentation as well. Users may look at rtxsrc/rtxErrCodes.h and rtxmlsrc/rtXmlErrCodes.h for up-to-date lists of what may be returned.
