In output of

/subsystem=elytron:read-resource-description(recursive=true)

, there is wrong description of simple-regex-realm-mapper / mapped-regex-realm-mapper "Definition of a custom RealmMapper" , what is probably copied from custom-realm-mapper.

In XSD, there is more proper

• mapped-regex-realm-mapper: "A RealmMapper implementaion that first uses a regular expression to extract the realm name, this is then converted using the configured mapping of realm names."
• simple-regex-realm-mapper: "A simple RealmMapper definition that attempts to extract the realm name using the capture group from the regular expression, if that does not provide a match then the delegate RealmMapper is used instead."
