Oh yes, this is the Pudels Kern :-) I am sorry I wasn't able to express
myself so concisely. However, I still think Sec. 7.6.4 in the YANG draft
can be understood as "mandatory to implement": >>If "mandatory" is
"true", the node must exist in a valid configuration if its parent node
exists.<< I guess it's again due to the different meanings of validity.
