Initial Values
When XML fields are created, as a design practice ensure that the fields are not created as null values. Ensure that when the fields are created, they are provided with an initial value.
|
<XMLDocument xmlns:xsi =http://www.w3.org/2001/XMLSchema-instance> |
The initial value is a value created during design time and the data field within the process will retain that value for each instance of the process when the process is instantiated.
