Description​

An error code. Error codes are often numeric, but in some environments they may be symbolic constants.

DocBook provides four elements for identifying the parts of an error message: ErrorCode, for the alphanumeric error code (e.g., “-2”); ErrorName, for the symbolic name of the error (e.g., “ENOENT”); ErrorText, for the text of the error message (e.g., “file not found”); and ErrorType, for the error type (e.g., “recoverable”).
