Writes to XmlEventWriter

Example

use xml::{EventWriter, EmitterConfig};
let mut writer =

let context = vec!["context-value-0", "context-value-1"];

    Enevolop[Static="static-value", FromContext=context[0] ][

      Body[][
        "Body Content"
      ]
      [{
        write_xml!(w,
          ContextItems[][
