This class is used by the DataAnnotationsModelMetadataProvider class, which is the default model metadata provider for MVC. By default, ModelMetadata objects are constructed using data taken from attributes, primarily from the System.ComponentModel and System.ComponentModel.DataAnnotations namespaces.
You can specify an alternative model metadata provider. For more information about ModelMetadata, see the entry ASP.NET MVC 2 Templates, Part 2: ModelMetadata on Brad Wilson's blog.
