[DevExpress Support Team: CLONED FROM S33097: Core - Make it possible to remove attributes information stored in the types info system]
Hi
There is some issue. Maybe this is bug.
RemoveAttribute method really removes attribute but if you add after that some other attribute the removed one is added back. See code:

C#
public override void CustomizeTypesInfo(DevExpress.ExpressApp.DC.ITypesInfo typesInfo) {  
    base.CustomizeTypesInfo(typesInfo);  
    ITypeInfo ti = typesInfo.FindTypeInfo(typeof(ITest));  
    BaseInfo bi = ti.FindMember("Name") as BaseInfo;  
    BrowsableAttribute attr = bi.FindAttribute<BrowsableAttribute>();  
    bi.RemoveAttribute(attr);  
    //here bi.FindAttribute<BrowsableAttribute>() == null  
    bi.AddAttribute(new DisplayNameAttribute("The name"));  
    //here bi.FindAttribute<BrowsableAttribute>() != null  
}

    This behavior is caused by domain components' specifics. I have forwarded your ticket to our developers to research if it is possible to overcome this limitation.
