• Distinguish between tables that will have a custom mortality-table specific API and those that should not. Tables that cannot be parsed into the existing API will inform the user that they are trying to load a table that is not a supported table.
• Provide a general API for all tables. When parsing the XTbML the only assumption we are making is that it is a valid XTbML file.
