An example of how to configure the check for names that are only letters in lowercase:

    <module name="RecordComponentName">
        <property name="format" value="^[a-z]+$"/>
    </module>
  </module>
</module>

class Example2 {
  record Rec1(int other) {}

  record Rec2(String Values) {} // violation, Name must match '^[a-z]+$'
