Older versions of ColdFusion MX removed all non-alphanumeric characters.
Prior to Updater 3, non-alphanumeric characters were not allowed in ColdFusion Component names, method names, or argument names. If a Web service parameter name contained any characters other than alphanumeric ones, such as the underscore in state_prov, ColdFusion omitted the special character from the name. This happens because older versions of ColdFusion MX use an Axis beta release that does not properly handle special characters in WSDL names.
