-A map from the full name of fields to the name of <<dynamic-templates, dynamic templates>.
+A map from the full name of fields to the name of <<dynamic-templates,dynamic templates>>.
 Defaults to an empty map. If a name matches a dynamic template, then that template will be
 applied regardless of other match predicates defined in the template. And if a field is
 already defined in the mapping, then this parameter won't be used.
