Controls whether or not channel filter values are sanitized by replacing any non letter or digit character with an '_'.

For example, if the channel key is specified as "/Orders/${Region}" and a filter of "Region=Asia/Pac" is given, then the filter will match all messages with the resolved key value of "/Orders/Asia_Pac" (rather than "/Orders/Asia/Pac").

*Default Value:

• • In 3.7 the value defaults to the value specified for nv.sma.cleanmessagekey.
  • In 3.8 onwards the default value is false.
