Drafter hangs on short document

Drafter hangs during semantic analysis of

# API name

## Group Instances

### Instance Model [/{instance-id}]


## Group Profiles

### Profiles Collection [/profiles]
            
#### Create Profile [POST]

+ Attributes (Profile)

+ Request (application/json)
   
        + Body
        
                {}
        
        + Schema 
        
                {}
        

### Profile [/v1/profiles/{id}]

+ Attributes (Profile)

I would expect a bunch of warnings and errors, but not an infinite loop.
