public interface 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.

```
java.lang.String getStringValue()
                         throws XPathException
```
    Convert the value to a string, using the serialization rules. For atomic values this is the same as a cast; for sequence values it gives a space-separated list. For nodes, it returns the string value of the node as defined in XDM.
    
    Throws:
    
    XPathException - The method can fail if evaluation of the value has been deferred, and if a failure occurs during the deferred evaluation. No failure is possible in the case of an AtomicValue or a Node.
  - getStringValueCS
```
java.lang.CharSequence getStringValueCS()
                                 throws XPathException
```
    Convert the value to a string, using the serialization rules, and returning the result as a CharSequence. In some cases this may be more efficient than obtaining the result as a string. For atomic values the result is the same as a cast; for sequence values it gives a space-separated list. For nodes, it returns the string value of the node as defined in XDM.
    
    Throws:
    
    XPathException - The method can fail if evaluation of the value has been deferred, and if a failure occurs during the deferred evaluation. No failure is possible in the case of an AtomicValue or a Node.
