attribute error w/ keyword uses: is_gramatically_valid does not exist

[GoogleCodeExporter]

Admittedly, this was probably bad .yang.  But a validating parser should not 
die given bad yang files.

    if s.keyword == "uses" and s.is_grammatically_valid == True:
AttributeError: 'Statement' object has no attribute 'is_grammatically_valid'

I changed the code near pyang/statements.py", line 885 to this which worked.  
But I am not sure if ignoring grammatically valid at this point is the right 
thing to do.

    # search for circular grouping definitions
    def validate_uses(s):
        if s.keyword == "uses" and ( (not hasattr(s, 'is_grammatically_valid')) or s.is_grammatically_valid == True):
            v_type_uses(ctx, s, no_error_report=True)

What version of the product are you using?

Could you attach an example YANG module which gives this error?

You solution is probably correct, but there might be a better way to fix this 
as well.

Sorry, the problem "magically" fixed itself as I was tweaking the .yang file.  
I should have saved the file.

Closing for now.
