public Optional<Output<String>> matchAttribute() {
        return Optional.ofNullable(this.matchAttribute);
    }
@return MatchAttribute requires that all devices in question have this attribute and that its type and value are the same across those devices.

For example, if you specified &#34;dra.example.com/numa&#34; (a hypothetical example!), then only devices in the same NUMA node will be chosen. A device which does not have that attribute will not be chosen. All devices should use a value of the same type for this attribute because that is part of its specification, but if one device doesn&#39;t, then it also will not be chosen.

Must include the domain qualifier.
