Hidden field

Can I in Voice xml do something like hidden fields in html forms?
I want a session id to be "posted" with the submit but can't figure out how to do this.
What I want to do is to set a "key value" pair that will not be changed by the client.
I am completely new to voicexml so sorry for the probably very basic question.

Claes.
