Core Schema

This chapter defines the details of the core PDRPolicyIDL schema. The schema is described using diagrams created with Altova’s XML Spy, which uses the following symbols.

The cardinality of the element (0..1, 1 exactly, 0..n, 1..n) is indicated by the border of the elements. Optional elements are drawn with a dashed line and required elements with a solid line. A maximum occurrence greater than one is indicated by a double border.

Optional element Min. occurrence = 0, Max. occurrence = 1

Required single element Min. occurrence = 1, Max. occurrence = 1

Required repeated element Min. occurrence = 1, Max. occurrence = unbounded

The content model of elements is symbolized on the left and right side of the element boxes. The left side indicates whether the element contains a simple type (text, numbers, dates, etc.) or a complex type (further elements). The right side of the element symbol indicates whether it contains child elements.

 

simple content

complex content

complex content with child elements

no element content (simple type, attributes only, or empty element)

Other symbols include these.

	A sequence of elements. The elements must appear exactly in the sequence in which they appear in the schema diagram.
	A choice of elements. Only a single element from those in the choice may appear at this position.
	The “all” model, in which the sequence of elements is not fixed.

Finally, if an element refers to a complex global type, the type is shown with a border and yellow background.
