Constraining coded values

Hello all,

Within an openEHR archetype we have a scenario where we have two elements that need to be coded. Element01 and Element02

Element01 can take on values "01","02","03",04"
Element02 can take on a subset of values from superset "A" thru "Z", depending on the value of Element01

How do we express this in an Observation archetype? Is it possible
