[MDSAL-527] Failed to find prefix for extension

Fri, 6 Mar 2020 10:32:52 +0000

The following three models:

module a {
  yang-version 1.1;
  namespace "a";
  prefix a;
 include b;}

submodule b {
  belongs-to a {
    prefix a;
  } import c {
   prefix c;
 }
 container foo {
     leaf bar {
       c:default-deny-all;
       type empty;
     }
  }
}

module c { 
 namespace "c";  
 prefix c;    
 extension default-deny-all {
   description "dsc";
    }
}

result in failing:
