xEL

xEL (or xEL, often stylized in various ways) typically refers to a framework or specification related to XML (Extensible Markup Language) for managing electronic data interchange (EDI) or for defining structured data formats in a standardized way. It encompasses the principles and practices used for encoding information in a format that is both machine-readable and human-readable. The "x" often signifies that it extends or modifies the original XML concept to meet specific needs in data representation or communication. As a term, it may appear in contexts such as software development, data management, web services, or standards frameworks where structured data is critical for interoperability among systems.
