<iNode>

| ## Text Encoding Initiative
### The XML Version of the TEI Guidelines # <iNode>

`<iNode>` | (intermediate (or internal) node) represents an intermediate (or internal) node of a tree.
Attributes | (In addition to global attributes)
`label` | gives a label for an intermediate node.
| Datatype: CDATA
| Values: A character string.
| Default: #IMPLIED
`value` | provides the value of an intermediate node, which is a feature structure or other analytic element.
| Datatype: IDREF
| Values: A valid identifier of a feature structure or other analytic element.
| Default: #IMPLIED
`children` | provides a list of identifiers of the elements which are the children of the intermediate node.
| Datatype: IDREFS
| Values: A list of identifiers.
| Default: #REQUIRED
`parent` | provides the identifier of the element which is the parent of this node.
| Datatype: IDREF
| Values: The identifier of the parent node.
| Default: #IMPLIED
`ord` | indicates whether or not the internal node is ordered.
| Datatype: (Y | N)
| Legal values are:
Y | indicates that the children of the intermediate node are ordered.
N | indicates that the children of the intermediate node are unordered.
| Default: #IMPLIED
Note | Use if and only if `ord=partial` is specified on the `<tree>` tag and the intermediate node has more than one child.
`follow` | provides an identifier of the element which this node follows.
| Datatype: IDREF
| Values: The identifier of another intermediate node or leaf of the tree.
| Default: #IMPLIED
Note | 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.
| Datatype: CDATA
| Values: A nonnegative integer.
| Default: #IMPLIED
Note | The in degree of an intermediate node is always 1.

Example

    <iNode id="pt1" label="PT" children="up1" parent="vb1" follow="pn1" outDegree="1"/>
