Some USoft Blend directives are designed to contain and return a subsystem of XML elements referred to as embedded XML.

Embedded XML is a specialised use of XML. It is specific to the USoft Blend framework. In each case, embedded XML has the structure of an XML document: it contains a single top-level node (the document node).

Example

This example shows XML embedded in a pc:Dialog element.

<pc:Dialog>
   <Form w="250">
      <Title>USoft Blend dialog</Title>
      <Label dx="5" dy="10" w="40" >This is a USoft Blend dialog.</Label>      
      <Button dy="20" newline="true"><Result>OK</Result>OK</Button>
   </Form>
</pc:Dialog>
