// Effective rows for Channel (type 53, ASHRAE 135-2020 Clause 12.53,
// Table 12-62), in table order with PROPERTY_LIST last. Only the rows the
// object serves are listed: the intrinsic-reporting rows,
// Reliability_Evaluation_Inhibit, Value_Source, the audit rows, Tags and the
// profile rows stay absent. Reliability is optional and present; it takes
// values other than NO_FAULT_DETECTED, so Clause 12.53.10 makes it writable
// while Out_Of_Service is TRUE.
// Present_Value, List_Of_Object_Property_References, Channel_Number and
// Control_Groups carry the table's W code. Out_Of_Service carries R but takes
// writes, as Clause 12.53.10 has a client set it to decouple the value from
// the members. Execution_Delay is optional and always present here; Clause
// 12.53.12 makes a present one writable. Allow_Group_Delay_Inhibit is
// optional, always present and writable here, so a client can configure
// WriteGroup's delay inhibit. Object_Name and Description take
// CharacterString writes.
