So every xml file I’ve met has this boiler plate line at the top, something like: <?xml version="1.0" encoding="UTF-8"?> But more often than not, it also has a url. But so does every json file I get from Azure. The other day I exported a power app and each app parameter/variable has its own folder with an xml file and a json file all, which each reference versioned schema and all sorts of stuff all to essentially just say “key: value” Who does this and why?

It is known as the XML declaration. It is not specific to any particular organization or group but is a standard part of the XML format itself. This declaration serves several important purposes: Version Information: It specifies the version of the XML standard being used. In this case, it's version 1.0, which is the most common version of XML. Character Encoding: It specifies the character encoding being used in the document. In this case, it's UTF-8, which is a widely used encoding that can represent a vast range of characters from different languages and character sets. Standards Compliance: It signals that the document adheres to the XML standard. This declaration helps parsers and software that process XML documents to interpret and handle the document correctly. Interoperability: By including this declaration, creators of XML documents ensure that their documents can be correctly interpreted and processed by a wide range of XML tools, libraries, and parsers. In essence, the XML declaration helps ensure that XML documents are self-describing and can be processed consistently by different software and systems. It's a crucial part of the XML standard and is included at the beginning of most XML documents to set the context for how the document should be handled.
