CTT Issues testing an OPC DA 3 Server

OPC Data Access 3.0 Compliance Test:
  Test Control Version: 1.00.3.1120
  Test Settings Version: 1.03.0.1120

reports errors that look like bugs in CTT.

Following are the screen dumps and explanations:

Issue 1:

Item property 5 reports a wrong data type. The server (checked with the debugger) returns the correct properties. Property 6 seems to be handled as property 5.
The property ID column doesn't show the correct IDs.
This error is reported only if case 3 is activated.

 

Issue 2:

An error is reported because the item property 2 (item value) is not returned for a write-only item. This is however correct. The item value must nor be returned for a write-only item.
The error is also reported for property 3 (quality) because the server handles quality as the value.
How do properties 3 and 4 ( quality and time stamp) need to be handled? Should they be returned for a write-only item?
