Re: CfC: Action name convention

Hi all,
I recently study the web intent spec, but I am confused about the action name.
As I know, the client invokes intent by constructing an Intent object, and it contains requested Intent action and type. Then UA will match the action and type to find in the registrations of the Service page. However, If developers can define any new actions for service pages in their domains, how a client page can know these action names when it requests an Intent be handled?
For example, I develop a web app which provides the service identified by a new action named" http://example.com/draw". How can other developers know there is an action named " http://example.com/draw"? Then they can add it to the intent object of client page.
Shouldn't it be standardized or managed by third party agent? Will the spec accept to add some other standard actions?
I appreciate your any answer.

Thanks and regards,
Yahui
