I've created a simple control to see what the attribute 'usage' on a property does in the form editor UI.
Whenever I included a usage=output I would get an exception during save of the form. See attached file.
I was able to configure the property and bind it to an attribute yet I couldn't save and publish the form.
Hi Menik,
This is actually a documentation defect , we accidently got it included. We have not exposed this functionality for public preview yet and hence the form editor throws error. Since you would be curious what it does, it is an internal mechanism to pass values across control directly without using any bound values which are needed currently. Please dont try using it though 🙂
And thanks for reporting, I have requested doc update.

I cannot attach .txt files so here's the content:
