We need 't' twice, because both TBuffer and SRV Resource classes expect a 't' binding prefix. The diagnostic engine takes in the resource class enum as an integer value to select which binding prefix character to expect in its message, so we need 0 ( the enum val for ResourceClass::SRV) and 3 (the enum val for ResourceClass::TBuffer) to both map to 't'.
