This namespace contains a lot of attributes for use in, I'm sure, many different applications. I'm curious to know which subset of the attributes in this namespace can be and are used in the Dynamic Data proxy class system, where the entity class is given an attribute that specifies a metadata type. That type contains properties with the same names as properties in the entity class, and the metadata provider builds MetaColumns using attributes on properties in these 'buddy' (proxy') classes.
So far my list includes, from System.ComponentModel.DataAnnotations:
Required, Range, DisplayFormat, StringLength, UIHint, DataType, Regular Expression, Display Column, Editable, and CustomValidation.
And from System.ComponentModel:
DisplayName, Description, and DefaultValue.
Am I missing any?
