+Steps to Reproduce:
+
+1. Create a custom text box control class. class MyTextBox : TextBox 
+{ }
+2. Put MyTextBox on a page with an asp:requiredvalidator tag.
+
+This causes two errors:
+a) System.ComponentModel.AttributeCollection:GetDefaultAttribute 
+throws MissingMethodException (I'll add a proposed patch soon.)
+b) With patch, you get the following exception
+
+System.Web.HttpException: Validator_bad_control_type: UserName 
+ControlToValidatein <0x000c9> 
+System.Web.UI.WebControls.BaseValidator:CheckControlValidationProperty
+ (string,string)
+
+Suspected cause:
+It appears that ValidationPropertyAttribute is not being properly 
+inherited into the custom textbox class. This is probably caused by 
+the fact that AttributeUsageAttribute.Inherited does not default to 
+true and some other cause I haven't tracked down yet.
