241** from each other. At the moment, mod_dav does not use this distinguishing
242** feature, but it could be used in the future to collapse <response> elements
243** into groups based on the error ID (and associated responsedescription).
244**
245** If a compute_desc is provided, then the error ID should be unique within
246** the context of the compute_desc function (so the function can figure out
247** what to filled into the desc).
248**
249** Basically, subsystems can ignore defining new error ID values if they want
250** to. The subsystems *do* need to return the predefined errors when
251** appropriate, so that mod_dav can figure out what to do. Subsystems can
252** simply leave the error ID field unfilled (zero) if there isn't an error
253** that must be placed there.
