Does tailf:cli-disallow-value allow us to enter wildcard or pattern?


I have a leaf string for interface and i do not want it to pick IP address as valid input. So was wondering if we can use tailf:cli-disallow-value to use wildcard or pattern?

The documentation says this CLI extension takes pattern.
So I assume you can use regexp, just try it to confirm (use one of the examples supplied with ConfD).
