Warns of imported module not used even when a symlink'd leaf exists for the imported module. #88

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Symlink a leaf in one module to an imported module.
2. Parse the module that includes the import definition.

eg; 

...
import SNMPv2-MIB {
       prefix mib2;
     }
...
tailf:symlink contact {
        tailf:path "/mib2:SNMPv2-MIB/mib2:system/mib2:sysContact"; 
 }

//tailf-common.yang
extension symlink {
  argument name {
    tailf:arg-type {
      type tailf:identifier;
    }
  }
...

What is the expected output? What do you see instead?
Should parse the yang provided the symlinks are valid.  The error is:
test.yang:27: warning: imported module SNMPv2-MIB not used

What version of the product are you using? On what operating system?
v1.3 on CentOS 6.3 (python 2.7.3)

This would be a tail-f specific enhancement; generic pyang does not know about 
tailf:symlink.
