 To control the workflow boundaries, this extension adds several custom nodes: `Subworkflow`, `Subworkflow Input`, and `Subworkflow Output`. These nodes work together to load and execute inner workflows while exposing their inputs and outputs on the outer workflow.

 `Subworkflow Input` and `Subworkflow Output` boundary names are read from their `slot_name` widget. For UI workflows this can come from either list-style or dictionary-style `widgets_values`; for API workflows it is read from the node's `inputs.slot_name`.

 ## Known Issues
 
 - [ ] The `Subworkflow` node progress can exceed 100%, sometimes reaching about 200%. Check with the upscale workflow example.
-- [ ] When no node is attached to an output of `Subworkflow`, an error occurs; it could be treated as an optional output.
 - [ ] Used paths with macro elements are not formatted currectly when used in inner workflow? (use Video Combine node with %date:yyyy-MM-dd%/WAN/Video)
 - [ ] Green progress borders appear on more than one node when executing a inner workflow as part of a larger workflow. These borders should be limited to the currently executing node(s) outer workflow.
 - [ ] The order if inputs/outputs on the `Subworkflow` node is undetermined (probably based on the order of nodes in the inner workflow JSON). Consider adding an option to control this order.
