This visualization example displays an XML Schema complex type definition for a 2D background element, showing how structured metadata attributes such as backColor and url are declared. The code uses XSLT to transform the schema, with the rendering relying on the xmta namespace for type references like SFColor and MFUrl. It demonstrates a declarative approach to defining visual properties within an XML-based configuration system, where the background layer can be customized through color and image URL attributes while optionally including an internal reference (IS). The example highlights how schema definitions encode rendering parameters without explicit drawing logic.
