In particular, as specified in [MS-WDV], section 2.2.3:

§ An Extended-error is an implementation-specific number that provides additional information about the cause of the error.

§ An Error-string is a percentage-encoded UTF-8 string, as specified in [RFC3986] section 2.1, that gives additional explanatory text about the cause of the error. This string is not significant to protocol operation and is intended only for display and logging purposes.
