It seems strange that the details that don't matter at all (like the filename) 
have lots

of rules that MUST be followed and the details that actually add standards 
value are left unspecified.

BALAZS2: Actually what is missing, unspecified?

 

The inline-schema is under-specified.

There is no way for the file reader to know what to expect as the child nodes 
of inline-schema.

 

The file writer can put anything there and a 3rd party reader tool is expected 
to support it.

 

           anydata inline-schema {
             mandatory true;
             description
               "Instance data corresponding to the YANG modules
                specified in the inline-module nodes defining the set
                of content defining YANG modules for this
                instance-data-set."; 

           }

BALAZS3:

IMO the anydata is specified.  The leaf-list inline-module defines the modules 
that define how anydata inline-schema should look like.

           anydata inline-schema {

             mandatory true;

             description

               "Instance data corresponding to the YANG modules

                specified in the inline-module ...

 

The fileReader/fileWriter shall look at the ‘leaf-list inline-module’ and from 
that it knows what to read/write.

 

I wanted to state that inline-schema anydata always follows the 
ietf-yang-library and maybe some YAMs augmenting it. However Juergen insisted 
in a more flexible solution.
