Attachments from subtasks:

To convert attachments from subtasks to text, simply substitute item cmw:attachment ?attach. with: ?item attachment:attachmentsTreeWithChildren ?attach. in the respective expression above.

If you want to include both attachments from item and subtasks, use assert function when writing an expression.
