PROTO Sony_BindSharedNode [ field SFNode transformNode NULL 
                              field SFNode scriptNode NULL ] {
}

• In transformNode field, a Transform node can be specified. A prototype instance that can appear anywhere Transform node can appear is also allowed.

• In scriptNode field, a Script node can be specified. A protoype instance that can appear anywhere Script node can appear is also allowed.

• In the prototype definition, Sony_BindSharedNode can appear in the definition of the body.

• If the same node is bound to Script nodes more than once, the first binding will win. (This rule may be change in the future. Don't rely on this rule).

  This rule is important in the following example:

  PROTO TEST1 [] {
    DEF TEST1_OBJ Transform { children [
      DEF TEST1_SCRIPT Script { ... }
      Sony_BindSharedNode {
        transformNode USE TEST1_OBJ
        scriptNode USE TEST1_SCRIPT
      ] }
    }
  }
  
  DEF TEST1_INSTANCE TEST1{}
  DEF NEW_SCRIPT Script{ ... }
  Sony_BindSharedNode {
    transformNode TEST1_INSTANCE
    scriptNode NEW_SCRIPT
  }
  

  In this example, TEST1_INSTANCE is bound twice: once inside the PROTO body, and at the last of the code. Even in this case the rule applies and the first binding (inside proto) will win.
