KRACOEUS-7323 fixed negotiation bugs

The Data dictionary changes are are to resolve audit validation problems from a disconnect between KNS and KRAD tags.
I believe one is for KRAD and the other for the KNS. There is no concept of validation patterns in KRAD, just constraints so I am guessing the one you removed was added to accomodate that. However, if we are going to run this document through the KNS DD validator (which is what we use for KNS docs) then we should probably only have the KNS version? I am not sure why this was added though, if it was added by accident or for a reason. Did you see two different errors for the same field? Can you check history to see where the additional one came from?
