/**
 * The config property contains a declaration of a single
 * configuration property for a ManagedConnectionFactory instance.
 * 
 * Each ManagedConnectionFactory instance creates connections to a specific EIS instance based on the properties configured on the ManagedConnectionFactory instance. The configurable properties are specified only once in the deployment descriptor, even though a resource adapter can be used to configure multiple ManagedConnnection-Factory instances (that create connections to different instances of the same EIS).
 * 
 * The declaration consists of an optional description, name, type
 * and an optional value of the configuration property. If the resource
 * adapter provider does not specify a value than the deployer is
 * responsible for providing a valid value for a configuration property.
 * 
 * Any bounds or well-defined values of properties should be described in the description.
