    Description: 
Similar to the ISBNValidator an ISSNValidator would be a great feature.

Conversion from ISSN to EAN by adding the prefix "977" and "00" right before 
the checkdigit to the issn code and recalculating the checksum similar to the 
ISBN conversion method.

Conversion from ISSN to EAN by adding the prefix "00977" to the issn code and 
recalculating the checksum similar to the ISBN conversion method would also be 
great.
