The value element
Release 2.0 - ...
This element provides a storage value to be used when an item is selected.
The storage value is determined by one of three methods, in order of precedence:
- The value of a node indicated by a Single Node Binding expression, if specified.
- The result of evaluating an XPath expression appearing in attribute value, if specified.
- The inline content of the value element (when neither the Single Node Binding nor the value attribute are expressed).
