Can you set a "required attribute" on control property?

  1. When creating a property for a server control can you set some sort of
    "required attribute", so that the developer sees the browser message you see
    when you leave off an attribute on a Microsoft control:

    Parser Error
    Description: An error occurred during the parsing of a resource required
    to service this request.
    Please review the following specific parse error
    details and modify your source file appropriately.
    Parser Error Message: The required attribute 'ContentPlaceHolderID' is
    not found on 'Content' control.
    Source Error:

    For right now I am just throwing HttpParseException during the Init, but
    that does not behave like Microsoft's controls.
