David Lloyd commented on WFCORE-1333:
-------------------------------------

While I agree that the server should not crash in this case, validating the attribute is the wrong answer.

Here are a few ways in which it could fail:
* The directory might be moved or deleted while the server is running
* The directory's permissions might be modified while the server is running
* The user might expect to be able to start the server and add the directory after the fact

The reason this fails is that a transient condition is being checked for in the configuration, but the configuration has no way to enforce the ongoing conformence to the constraint.

The right answer is for the deployment scanner to dynamically be able to handle the directory appearing and disappearing.  The user should be allowed to set a non-existent {{path}} component, which causes the deployment scanner to find no files until the path is created.  The {{relative-to}} component, however, should be validated as that is a model integrity check.
