+/**
+ * Sets the type of metadata to use. Metadata is encoded in JSON, and each property
+ * in the JSON will become a property of the element itself.
+ *
+ * There are three supported types of metadata storage:
+ *
+ *   attr:  Inside an attribute. The name parameter indicates *which* attribute.
+ *          
+ *   class: Inside the class attribute, wrapped in curly braces: { }
+ *   
+ *   elem:  Inside a child element (e.g. a script tag). The
+ *          name parameter indicates *which* element.
+ *          
+ * The metadata for an element is loaded the first time the element is accessed via jQuery.
+ *
+ * As a result, you can define the metadata type, use $(expr) to load the metadata into the elements
+ * matched by expr, then redefine the metadata type and run another $(expr) for other elements.
+ * 
+ * @name $.metadata.setType
+ *
+ * @example <p id="one" class="some_class {item_id: 1, item_label: 'Label'}">This is a p</p>
+ * @before $.metadata.setType("class")
+ * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
+ * @desc Reads metadata from the class attribute
+ * 
+ * @example <p id="one" class="some_class" data="{item_id: 1, item_label: 'Label'}">This is a p</p>
+ * @before $.metadata.setType("attr", "data")
+ * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
+ * @desc Reads metadata from a "data" attribute
+ * 
+ * @example <p id="one" class="some_class"><script>{item_id: 1, item_label: 'Label'}</script>This is a p</p>
+ * @before $.metadata.setType("elem", "script")
+ * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
+ * @desc Reads metadata from a nested script element
+ * 
+ * @param String type The encoding type
+ * @param String name The name of the attribute to be used to get metadata (optional)
+ * @cat Plugins/Metadata
+ * @descr Sets the type of encoding to be used when loading metadata for the first time
+ * @type undefined
