Hi,

Not sure whether this has been requested before but has it ever been considered 
to support higher versions of XPATH in YANG?  As far as I remember only XPATH 
1.0 is supported in YANG although the RFC mentions adopting of XPATH 2.0 with 
respect to handling of unprefixed names.  RFC6020bis lists a set of functions 
that have been added and that are available in an XPATH context.  XPATH itself 
at this moment is at version 3.1.  Some questions:
- are there any plans to follow the XPATH evolution in YANG?
- to me at least it is not specifically clear what is and what is not supported 
w.r.t. XPATH in YANG.  Is there no clarification required in this context?

Certain checks can't be expressed using an XPATH and require XQUERY (e.g. when 
one need to follow a linked list in case of a lookup of a specific node).  Are 
there any plans to include support for XQUERY in YANG?

I think it is a good idea to capture ideas like this, but I also think that 
such ideas should be discussed on the ML.  But maybe that's what you meant.
