Using UML features


I am not able to use some of the UML features using VP-UML. Let me know the steps to do the same, or the reference document. I went through VP guide but unable to find there.

  1. How to show in a class diagram the constrain for subtypes {disjoint, complete}.

  2. In case of activity diagram, for a decision node, how do we write the “condition” statement. Do we need to use “text box”?

  3. In case of composite structure diagram, for showing composite objects, do I need to use “class” and name it like
    rearWheel: Wheel [2]
    Or there is any other direct option to show objects and specifying multiplicity?

  4. For referencing another Activity diagram, which standard diagram should I use to be used as a reference.

I wish am clear about my query.
