Hi Med,

I am not aware of which data nodes are sensitive in this module. If you
find any, please point them out.

But I am aware that the extended modules (e.g., examples in the appendix)
may include sensitive data. Especially, the "data-source" node. So I added
a new paragraph [1] to clarify this. Do you think it is enough?

Thanks,
Jensen
