TECH 101: XML (Extensible Markup Language)
Yes, technically it should be EML. XML is used to define documents with a standard format that can be read by any XML-compatible application. The language can be used with HTML pages, but XML itself is not a markup language. Instead, it is a "metalanguage" that can be used to create markup languages for specific applications. Basically, XML allows you to create a database of information without having an actual database. While it is commonly used in Web applications, many other programs can use XML documents as well.
