Interesting challenge, the closest I could come up with is;

define verb chocolate
  image sys$login:chocolate
  qualifier list, syntax=list_syntax
  parameter p1, label=hostname,prompt="Host Name"
  qualifier brief
  qualifier full
  qualifier oven, value (type=$number)
  disallow (brief and full)
  disallow (not hostname) ! Give an error if no hostname

  define syntax list_syntax
    qualifier list
    parameter p1, label=hostname
    disallow (hostname)  ! Give an error if they type chocolate /list
www.digital.com

But it would be better (I think) to define the syntax as;
    $ CHOCOLATE /LIST
    $ CHOCOLATE /HOST hostname [/BRIEF] [/FULL] [/OVEN=value]
If you go that route then you will have something like;

define verb chocolate
  image chocolate
  qualifier list, syntax=list_syntax
  qualifier host, syntax=host_syntax
  disallow (not list and not host)

  define syntax host_syntax
    parameter p1, label=hostname,prompt="Host Name", value (required)
    qualifier host
    qualifier brief
    qualifier full
    qualifier oven, value (type=$number)
    disallow (brief and full)

  define syntax list_syntax
    qualifier list
