I would’ve not use nullable. 

I would change the pattern to be “10 upper-lower or null”  I’m not sure {0,10} would be what you want.

    Indeed, I do prefer to use a pattern only
    For example:

    username:
   type: string
   pattern: "^[a-zA-Z]{0,10}$"
   example: John

     or this one:

    username:
  type: string
  pattern: "^[a-zA-Z]{10}$|^$"
  example: John

     

    In any cases, "nullable: true" seems to interact quiet differently, depending on the other keywords (see this post and this one for more details). 

    So my question is: in which case,  "nullable: true" is the most appropriate?
