EE and bindable property placeholder support are two different subsystems that both use ${} as keyword, and while EE uses namespaces and bindable property placeholders does not. Bindable property placeholders should be able to be created as follows:

<key name="to" value="${properties.adminEmail}" />

Talking this through with Peter: You won't be able to use "event" as a prefix, clearly, so we could check to see if the framework is loading in order to support backward compat. By default bindable property placeholders could be assumed to be placing "properties." in front of their name.

My expectation would be that the "properties" prefix would be used for clarity.

@Brian, yeah I would agree the "best practice" would be to prefix the "scope" name for clarity. Kurt's comment was in regards to keeping things backwards compatible (BC) with the old way of bindable property place holders.
