[xfire-user] BigInteger in wsdl generation

[Karthikeyan M]

During wsdl generation, BigIntegers defined as parameter or bean 
property is being translated into a custom type called BigInteger 
instead of xsd:integer.
Is there a specific reason why xsd:integer 
(http://www.w3.org/TR/xmlschema-2/#integer) can't be used for BigIntegers?
