    Allowed operation between jmx attribute and reference value:
    • == equals
    • != not equals
    • > greater than (&gt;)
    • >= greater than or equals (&gt;=)
    • < lesser than (&lt;)
    • <= lesser than or equals (&lt;=)
    NOTE: For numeric expressions the type must be set and use xml entities as operations.
    As type we currently support long and double.
