No compliant JSF system does.

You can, however, define parameters that will be passed as part of the request submit, and IIRC, that's just a matter of putting <f:param> children under an <h:commandButton> (or commandLink) and can be done with core JSF.

Getting the parameter itself in the action processor means having to dig into internal structures in a way that generally means you're not using JSF the way it was designed for. Use of parameters in well-designed JSF apps isn't unknown, but it's not all that common, since the backing beans and datamodels cover the most common situations without the need to get that complicated.
