Coercion Paths

The following diagram shows how coercion rules are connected.

The expression that coerces a source node type to a target node type is built by following the path that connects them. A dotted line indicates a coercion that does not require an explicit conversion function. This occurs whenever the source type is a specialization of the target type. For example, every measure is a member so you can use measures without conversion wherever a member is required.
