Structs are XML-RPC representation of PHP’s associative arrays. Each item has a named key and a value pair. A single struct element defines a struct. Each item has one member element, each member element has a required name element, which names the item, and one value element which represents the value. Also, like arrays, the value element follows the definition rules of scalar values in XML-RPC.
