Question on interaction management in Multimodal Interaction Framework

Hi,

I have read the "Specification of interaction management component" and the rest of the document and have some questions on it:
1) Do I understand right that the interaction management may be part of a client (e.g. web browser) and may also be part of a server (e.g. web server)?

2) What are the preferred protocols/mark-up languages to communicate with the interaction manager?

3) In there any more detailed description of the interaction manager available?

Thanks for your help!
