Re: [Lime] draft-ietf-lime-yang-oam-model-07.txt: YANG compilation error

[Benoit Claise <[e-mail]>]

Dear authors,

Please solve the compilation issue with your draft.

I've been adding a new column to the report at 
http://www.claise.be/IETFYANGPageCompilation.html, where from you can 
download the extracted YANG module.
Lately, I received some concerns about the line number from the pyang 
output that could not easily match to the YANG module line number.
Indeed the pyang error line number is the one from the YANG module and 
not the IETF draft. This is specifically a concern with xpath issues.
On top of that, some people use rfcstrip as opposed to xym.py to extract 
the YANG modules from IETF draft.

The error for your draft is:

    ietf-conn-oam.yang:351: error: the node 'MD-name-format' from module
    'ietf-conn-oam' is not found
    ietf-conn-oam.yang:351: error: the node 'name-format-null' from
    module 'ietf-conn-oam' (in node 'MD-name-null' from 'ietf-conn-oam')
    is not found
    ietf-conn-oam.yang:391: error: the node 'MA-name-format' from module
    'ietf-conn-oam' (in node 'domain' from 'ietf-conn-oam') is not found
    ietf-conn-oam.yang:391: error: the node 'name-format-null' from
    module 'ietf-conn-oam' (in node 'MA-name-null' from 'ietf-conn-oam')
    is not found

Downloading the YANG, I confirm that this is a xpath issue.

     choice MD-name {
       case MD-name-null {
         leaf MD-name-null {
         when "../../../MD-name-format = name-format-null" 
{                     <= line 351
         description
         "MD name format is equal to null format.";
         }
         type empty;
         description
         "MD name Null.";
         }
       }
       description
         "MD name.";
     }


   grouping MA-name {
     description
       "MA name";
     leaf MA-name-format {
       type identityref {
         base name-format;
       }
       description
         "Ma name format";
     }
     choice MA-name {
      case MA-name-null {
       leaf MA-name-null {
        when "../../../MA-name-format = name-format-null" 
{               <= line 391
        description
          "MA";
       }
         type empty;
         description
         "empty";
         }
       }
       description
         "MA name";
     }
   }
