------------------------------

             Summary: ISBN style numbers outside ISBN range returning true for isValid
                 Key: VALIDATOR-447
                 URL: https://issues.apache.org/jira/browse/VALIDATOR-447
             Project: Commons Validator
          Issue Type: Improvement
          Components: Routines
            Reporter: Alex
         Attachments: RangeMessage.xml

All 13 digit EANs with the 979 prefix are validating as ISBNs (ISBNValidator). There are 2
issues with this.
 # 979-0 prefixed numbers are allocated to the ISMN agency and represent music works. [https://www.ismn-international.org/whatis.html]
 # 979-[2-9] are unassigned at present, that is they have not yet been allocated to a country
agency (or another authority).
see attached xml (from [www.isbn-international.org/export_rangemessage.xml|http://www.isbn-international.org/export_rangemessage.xml]
[^RangeMessage.xml] ) for the current valid ranges for ISBN 
and [https://en.wikipedia.org/wiki/List_of_ISBN_identifier_groups#Identifiers_of_the_979-_prefix]

An example unassigned 'ISBN' is 9792222222223
