Remarks
Must be implemented, must not throw an ASCOM.PropertyNotImplementedException.
The returned object contains entries for each value. For each entry, the Key property is the value's name, and the Value property is the string value itself.
This property must return an empty list if no video frame metadata is provided.The Keys is a single word, or multiple words joined by underscore characters, that sensibly describes the variable. It is recommended that Keys should be a maximum of 16 characters for legibility and all upper case.
The KeyValuePair objects are instances of the KeyValuePair class
