Hi Juergen,
What we don't like in current RFC6991 is the type is uint8 which doesn't allow
fraction.
For the range, if the defintion can cover the our range(0..99.9999), it will be
acceptable.
In your suggestion below, does that mean the base defintion is without range,
while refined types can chosse the range they like?
BR,
Amy

Well, the draft-ye-ccamp-mw-topo-yang-02 definition excludes 100%,
which is likely not generally useful. In fact, even 150% can be in
some contexts a perfectly sensible percentage. So we may need to
provide some flexibility here, i.e., having a base time where the
range can be refined and refined types with an upper limit set to 100%
for use in situations where this limit is sensible.
The more difficult aspect seems to be precision, I am not sure YANG
allows subtyping the fractional part. RFC 7950 seems to be silent
about this and in the general case this would not be meaningful. But
in this particular case, when the number range is limited, it would
actually be OK to allow this (but then we have to have a limit and
we can't set the upper limit to max).
