Workflow Foundation TrackingDataItemValue collection property

[M]

I want to filter tracking information from a SqlWorkflowTrackingQuery
using a TrackingDataItemValue.

The SDK explains to me that the TrackingDataItemValue needs the
following fields to be set: ActivityName, MemberName, Value.

The SDK explains also to me that it is possible to assign a Collection
property member to the MemberName Property. But what the SDK not
explains is how to do this. I mean, What notation is required to get
this work?

Can anyone provide me the correct notation for this?

For example here some code to visualize what I need to do:

---------------------------- START EXAMPLE
-------------------------------------

List<SqlTrackingWorkflowInstancequeriedWorkflows = new
List<SqlTrackingWorkflowInstance>();
SqlTrackingQuery query = new SqlTrackingQuery("MyConnectionString");
SqlTrackingQueryOptions options = new SqlTrackingQueryOptions();

options.StatusMinDateTime = DateTime.MinValue;
options.TrackingDataItems.Add(
new TrackingDataItemValue("MyActivityName",
"MyCollectionPropertyName[MemberName??]", "MyValue"));

queriedWorkflows = query.GetWorkflows(options);
---------------------------- END EXAMPLE
-------------------------------------

Sow what is the correct notation of
"MyCollectionPropertyName[MemberName??]" ??
Best regards,
