+** Save node
+
+*** Description
+
+  A <<save>> node is used to save information about a

+*--------------*-------+
+| <<force>>    | If "true", save resource even if this resource is already stored in persistent storage
+*--------------*-------+
+| <<pfx>>      | Prefix to be prepended to variable names, when attributes are set in SvcLogicContext
+*--------------*-------+
+
+*** Parameters
+
+  Values to save (columns) are specified as parameters, with each name
+  corresponding to a column name and each value corresponding to the
+  value to set.
+
+*** Outcomes
+
+*-----------*-------+
+| <<success>>  | Resource successfully saved
+*-----------*-------+

+    key="vnf-name = $requests.vnf.vnf-name" force="true"
+    pfx="requests.vnf">
+    <parameter name="vnf-name"
+        value="`$requests.cust-country-code + $requests.cust-id + $requests.cust-city + $requests.cust-state + '001VCE'`" />
