Modul

Attribute

value

provides the value of an intermediate node, which is a feature structure or other analytic element.

Zustand	Vorgeschrieben wenn zutreffend
Datentyp	<rng:ref name="data.pointer"/> data.pointer
Werte	A valid identifier of a feature structure or other analytic element.

children

provides a list of identifiers of the elements which are the children of the intermediate node.

Zustand	Obligatorisch
Datentyp	1–∞ occurrences of <rng:ref name="data.pointer"/> data.pointer separated by whitespace
Werte	A list of identifiers.

parent

provides the identifier of the element which is the parent of this node.

Zustand	Optional
Datentyp	<rng:ref name="data.pointer"/> data.pointer
Werte	The identifier of the parent node.

ord

(ordered) indicates whether or not the internal node is ordered.

Zustand	Optional
Datentyp	<rng:ref name="data.xTruthValue"/> data.xTruthValue
Anmerkung	The value true indicates that the children of the intermediate node are ordered, whereas false indicates the are unordered. Use if and only if ord is specified as partial on the <tree> element and the intermediate node has more than one child.

provides an identifier of the element which this node follows.

Zustand	Vorgeschrieben wenn zutreffend
Datentyp	<rng:ref name="data.pointer"/> data.pointer
Werte	The identifier of another intermediate node or leaf of the tree.
Anmerkung	If the tree is unordered or partially ordered, this attribute has the property of fixing the relative order of the intermediate node and the element which is the value of the attribute.

outDegree

gives the out degree of an intermediate node, the number of its children.

Zustand	Optional
Datentyp	<rng:ref name="data.count"/> data.count
Werte	A nonnegative integer.
Anmerkung	The in degree of an intermediate node is always 1.
