Cast Iron CDK XML file
Your XML file defines what activities your plug-in performs. Every activity in your XML file must be mapped to an operation defined in the WSDL file.
XML has emerged as the universal language for representing and transmitting structured data that is independent of programming language, software platform, and hardware. For your development project, you can use any text editor or a XML-compliant authoring tool to create your XML file. Your file must conform to the rules of your schema files or your plug-in will fail.
