# RFC 7950 Sections 9.13 and 14 says that:
#   Predicates are used only for specifying the values for the key nodes for list entries
# but does not explicitly say that list nodes can skip them
# And in RFC8341 node-instance-identifiers are defined as:
#   All the same rules as an instance-identifier apply, except that predicates for keys are optional.
#   If a key predicate is missing, then the node-instance-identifier represents all possible server
#   instances for that key.
