21  * implements a map that maps to the sqlValue property of
22  * the SessionParam's in the SessionParamPool.
23  * Not all methods are implemented but enough to use
24  * the map as a generic target for wcf forms.
25  * <p />
26  * In a wcf:form xml definition, e.g. you can set the modelReference
27  * attribute to "sqlValue.foo". Then the user will be able to
28  * change the sqlValue of the SessionParam named "foo".
29  * <p/>
30  * If you put a value into the map, the corresponding SqlParam
31  * will be created.
