Hi ,

I have a query on Link in / Link Out Nodes.  
Documentation says : " **Note:** Links cannot be created going into, or out of, a subflow."

Does it mean - that

1. we cannot have Link in / Link Out within a subflow ?

- Or

1. we cannot have one end point within a subflow and the other end point outside subflow.

2. Will the below be valid ? It works. But want to be sure i understand it right.

1. You can’t have one end in and one end out.
