To a user of the schema-mount, it is important to be able to visualize all key elements of the mounting mechanism: mount-point, mounted schema module, and parent-reference. The details can be worked out, but if any of these elements were not useful in the presentation, it would be questionable whether it had well-specified in the schema mount draft. > -----Original Message----- > From: netmod [mailto:netmod-bounces@ietf.org] On Behalf Of Martin > Bjorklund > Sent: Monday, September 25, 2017 1:39 PM > To: acee@cisco.com > Cc: netmod@ietf.org > Subject: Re: [netmod] Proposal to enhance the YANG tree output > > "Acee Lindem (acee)" <acee@cisco.com> wrote: > > Martin, Lada, et al, > > > > While I don’t think we need additional annotations that Joe had > > prototyped (at least not as the default), I strongly believe we need > > to keep the ‘@‘ and ‘/‘ in the tree output for schema mount. > > Can you explain what information "/" gives the reader?

[Xufeng] Because the schema mount draft allows an augmenting module not to be listed in the mounted schema list. The following two examples show two different configurations: +--mp root +--rw rt:routing/ | +--rw router-id? yang:dotted-quad | +--rw control-plane-protocols | +--rw control-plane-protocol* [type name] | +--rw ospf:ospf/ where ospf augments rt, and has been listed in the mounting schema list. +--mp root +--rw rt:routing/ | +--rw router-id? yang:dotted-quad | +--rw control-plane-protocols | +--rw control-plane-protocol* [type name] | +--rw ospf:ospf where ospf augments rt, and has not been listed in the mounting schema list. > > > > Then consider: > > +--ro if:interfaces@ > > and > > +--ro if:interfaces > +-- if:interface@ > > and > > +--ro if:interfaces@ > +-- if:interface@ > > > Which ones are legal, and what do they mean? > [Xufeng] The display shows the result of the XPath, right?
