Cannot create or modify NACM data node access rule with path using JSON encoding

[olofhagsand]

If you want to modify NACM RFC8341 data node paths dynamically (ie not only given at startup time), you cannot do this using JSON encoding. The reason is that paths use instance-identifiers which need a namespace context which are not given by JSON.
XML encoding works fine.
Example using XML encoding:

     <rule-list>
       <name>guest-acl</name>
       <group>guest</group>
       <rule>
         <name>deny-nacm</name>
         <path xmlns:n="urn:ietf:params:xml:ns:yang:ietf-netconf-acm">   
           /n:nacm   <<<-----------
         </path>
