Check Value with Tailored Algorithm

You can implement a custom rule via the CodeRule attribute. Code rules are usually designed for the following purposes:
- to check an object using a highly tailored algorithm;
- to apply a rule to an object that is implemented in a referenced assembly, without using the Model Editor.
Here, a custom rule is implemented for the CodeRuleObject type objects. It uses the following algorithm to check objects:
- if PersonName is not specified, a validation error is raised;
- if PersonName is specified, Sex is set to Male, but TitleOfCourtesy is not set to "Mr", a validation error is raised;
- if PersonName is specified, Sex is set to Female, but TitleOfCourtesy is set to "Mr", a validation error is raised;
- in other cases, the rule is valid.
For each case a rule is broken, a message template is specified to be written in the Validation Error window.
This rule is checked when saving an object.
