Summary
In this chapter we have learned how to use the target type to set the context for a rule. We then learned how to write a few Filter Expressions to reduce the shapes that need to be processed, and finally how to write Test Expressions that can raise issues. There are probably more expressions that could be written but we can work those out when we have specific requirements.
In the next chapter, we will learn how to publish custom templates with validation rules for deployment to other Visio 2013 Professional users.
