Introduction

These are the diagnostics defined for use with SRW. The Number is the code to be returned to identify the diagnostic. The details format is what should be returned in the details field. If this is blank then the format is undefined and the server may return whatever it feels appropriate, including nothing. Some of the diagnostics from earlier versions have been deprecated, however they are still listed here, suitably marked, for reference.
