XFDL files are, mostly, used for business matters. These XML structured files often contain legally-binding contracts or forms. This file type was developed to ensure the auditability, security, non-repudiation and preservation of sensible business transaction data. The XFDL forms are standardized and can be used by different business for different purposes. Its usage is quite common in eCommerce.
