Missing Docs for Spring JavaScript

Hi,

I was trying out Spring Web Flow. Found Spring JavaScript very intersting and useful but where are api docs of Spring JavaScript.

Eg. I was using

Code:

---

  Spring.addDecoration(new Spring.ElementDecoration({
                                        elementId : "username",
                                        widgetType : "dijit.form.ValidationTextBox",
                                        popup: true,
                                        widgetAttrs : { promptMessage : "Empty User Name. Please enter a valid user name.", required : true }}));

---

How can I find out what are all possible config options of Spring.ElementDecoration in addition to elementId ,widgetType ,popup etc.

What are other apis in addition to Spring.addDecoration, Spring.ElementDecoration

Reference pdf only gives brief introduction.

Can you please direct me to proper resources.

Thanks....:confused:
