Review Comment:
The `name` attribute of a decision is mandatory by specs, but I created that
method to programmatically navigate the tree from a leaf element to its parent
decision/bkm.
But
`if (dmnElement.getParentDRDElement() == null || dmnElement ==
dmnElement.getParentDRDElement()) {`
actually is based on our implementation, and I'm not 100% sure that,
somehow, we could have a situation where a Conditional does not have any -
e.g.: what if it is defined inside an imported model, and referred to a
decision that is in the importing model (just e.g. - I need to review the spec
for this case).
So, I think it would be safer - for the moment being - to simply return
something like `(undefined)` - opr similar.
Wdyt ? Does this make sense ?
