transport format. As long as the receiving component runs on a platform that is available to the XML Analyzer, it can provide many features while ensuring interoperability. When transferring through XML, the receiver no longer has to be a COM object. XML is a simple but powerful text-based standard that has recently become widely accepted by the industry, so there is reason to expect an XML analyzer on almost every platform. In this way, the receiving component will not have any architectural l
