xCBL 3.5 XML DTD Version

The XML 1.0 spec provides for the use of XML Document Type Definitions (DTDs), and this type of validation is supported by almost all of the validating XML tools on the market today. xCBL 3.5 is provided in XML DTD form, to allow for it's widest use in XML applications of all types. Needless to say, XML DTDs do not give you the strong typing characteristic of XML Schema languages such as SOX or XDR.
