"and then use this SimpleType in various DataSourceField definitions across their application for use with any DataBoundComponent like a ListGrid, TreeGrid, DynamicForm etc.</p>" +
"<p>This is a powerful feature allows creation and reuse of domain specific \"primitive\" data types or types in the enterprises Common Data Model (CDM)." +
"<p>Enter a bad zip code (eg just \"123\") and press \"Validate\" to receive a validation error. Custom types can be declared based on built-in validators and re-used in multiple DataSources.</p>";
