Examples of ValueRepresentation

client.net.sf.saxon.ce.om.ValueRepresentation
A ValueRepresentation is a representation of a Value. This is a marker interface used to represent the union of two classes: Value, and NodeInfo. Either of these two classes can be used to represent a value. The class is used primarily to represent the value of a variable.
This class is intended primarily for internal use, and should not be considered part of the Saxon public API.
