an intermediate step would be to check if the expression provide a default value and use it.

We could check if for the pattern $\{exp:default\} and use the default value for the transformation.
This is less involving than resolving the expression and would allow a greater compatibility for legacy versions that could safely failback on the default value.

> We need to be able to properly handle values which are getting changed to allow expressions. 
> The problem is that older HCs won't understand the expression value, therefore they need be resolved before sending the initial model. At this point this can only be done against domain/host specific system properties. Server-group and server level overrides would be lost when starting a managed server.
