Not sure how we should standardize this. Current SpEL is #{, and KRAD extends this to support @{ so they can do more dynamic evaluations at render time instead of during spring initialization. Is one version better than the other for this?? This syntax seems to be a mix of SpEL/KRAD EL and Java annotations. In SpEL I feel like it would be more like #{paramReference("KC-PD", "Document", "name")} and in annotations it would be @ParameterReference(ns="KC-PD", c="Document", n="name"). So how much do we care about matching up to a similar syntax?
