Output of "Describe relation" with bag

    Hi,

    Can’t understand the output of ‘DESCRIBE words’ ,
    learned that format of relations with bags is “words: {group:chararray, a:bag{:tuple(csv:chararray)}}
    But the format of relation “words” is something different. Please correct me if i am wrong
    grunt> describe a;
    a: {samptxt: chararray}
    grunt> describe fltr;
    fltr: {csv: chararray}
    grunt> describe words;
    words: {bag_of_tokenTuples_from_csv::token: chararray}
    grunt>

    Output of ” Illustrate words;”
