LPS-33811 Cleaning up the Element parameters from SMDHs

Hey Mike,

This is the change set we were talking about. Basically these changes allow us to clean up the code big time, also to access the necessary XML Elements from everywhere during staging. This is needed for the DL portlet changes, and for others as well.

Of course the manifest will affect this change as well, but we have to code the SMDHs first.

Thanks,

Máté
