The XUI specification consists of a quantity of absolutely addressed visualization components (component), which connects an element from an XML instance with a representation type and the appropriate parameterizing possibilities for this type. In addition, global rules (rule) can be defined. These rules can be used in different contexts. These rules can be used in different contexts. See the relevant section, further in this document.

XUI schema - Logical structure

Each XUI component (component) in the XUI document is identified by clear addressing. This addressing corresponds to the XPath in the target instance (XML instance). For details see Addressing by means of XPath. This described nesting of the XML schema representation types is not repeated in the XUI specification, in order to obtain loose coupling (as small as possible) between the structural and the visual representation nesting, expressed in the XML schema. Instead, each representation type is identified only by absolute addressing (XPath).

<XUI>

<style/>
<behaviour/>
</component>
</XUI>

Individual nodes or whole quantities of nodes of the XML instance are addressed with an XPath expression (XPath statement). The parameterizing possibilities within the < style > and < behaviour > section vary from one type to another. All representation-and behavior-relevant XUI parameters are described further in this document.
