A validation method is a method with a ValidationMethod attribute and a ValidationContext parameter. A validation method is enabled if one of the ValidationCategories specified in its ValidationMethod attribute matches one of those in the categories parameter. Validation methods in the element's own class and all of its base classes are called.//A validation method can log an error or warning message using the Log methods in the validation context.//Validation methods can use the cache methods in the validation context to pass information from one method to another.
