Missing <?xml - SVG files are XML files

Please consider adding <?xml version="1.0" encoding="UTF-8" standalone="no"?> to downloaded files. The standard says: https://www.w3.org/TR/SVG11/struct.html#NewDocument

SVG-s copied to the clipboard could remain the way they are as people tend to paste them into HTML source code.

Thank you!

SVGO is an Optimizer. xml instruction is not necessary to use .svg files in many environments. If you need to add somethinng use svgo package directly and write custom plugin like this

const addXmlInstructionPlugin = {
  type: 'visitor',
  name: 'add-xml-instruction',
  fn: () => {
    let hasXmlInstruction = false;
    return {
      instruction: {
        enter: node => {
          if (node.name === 'xml') {
            hasXmlInstruction = true;
          }
        }
     },
      root: {
        exit: node => {
          if (hasXmlInstruction === false) {
            node.children.push({
              type: 'instruction',
              name: 'xml',
              value: 'version="1.0" encoding="utf-8"',
            })
          }
        }
      }
    }
  }
}
