Lada, Robert
The other angle from which this might be approached is that the I-D
already says
" Using the "type" statement, a type is specified for the annotation
value according to the same rules as for YANG "leaf" type. "
while rfc6020bis says
" The "leaf" statement is used to define a scalar variable of a
particular built-in or derived type."
so if you know your YANG off by heart, then you will know that
annotations must be scalar. I agree that the text needs to be clearer.
Perhaps,
OLD
" o annotations are scalar values and cannot be further structured;"
NEW
"Annotations obey the same rules as for a YANG "leaf" type [rfc6020bis
s.7.6] and so are limited to scalar variables."
There is no 'leaf type' in YANG. YANG has leaf nodes in the schema
tree. An annotation is not a node in the schema tree. Perhaps
something like this:
An annotation carries a single value. The type substatement, which
must be present, takes as an argument the name of an existing
built-in or derived type and the value of the annotation must match
this type. See Section 7.4 of [RFC6020bis] for details.
Looks good, thanks. Robert, Tom, do you think this text is sufficient?
