<root>

<root> (root node) represents the root node of a tree.
Attributes (In addition to global attributes)
label gives a label for a root node.
Datatype: CDATA
Values: A character string.
Default: #IMPLIED
value provides the value of the root, 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 root node.
Datatype: IDREFS
Values: A list of valid identifiers.
Default: #IMPLIED
Note

If the root has no children (i.e., the tree is `trivial'), then the children attribute must be omitted. For technical reasons, it cannot be specified as <root children=''>.
ord indicates whether or not the root is ordered.
Datatype: (Y | N)
Legal values are:
Y indicates that the children of the root are ordered.
N indicates that the children of the root are unordered.
Default: #IMPLIED
Note

Use if and only if ord=partial is specified on the <tree> tag and the root has more than one child.
outDegree gives the out degree of the root, the number of its children.
Datatype: CDATA
Values: A nonnegative integer.
Default: #IMPLIED
Note

The in degree of the root is always 0.
Example 
<root id="vp1" label="VP" children="vb1 pn1" outDegree="2"/>
