XML Schema Refactoring is an XML schema management, analysis and transformation toolset for XML Schemas (XSD). It supports XSD-to-XSD transformations as well as XSD-to-Combinatorial Test Model (CTM) and XSD-to-XML Builder (MPX) transformations, when integrated with other modules.
The transformation features have been primarily designed to make the customization of industry standard XML Schemas a standalone and scalable process. The main driver is to allow new versions of schemas to be quickly adopted with minimum efforts, an important factor in maintaining the relevance and value of a standard.
Transformations are also an effective mechanism to balance the generality of a standard with the need to customize for a particular implementation. By simplifying overly complex content models, productivity and runtime costs can be significantly improved.
