If the format needs to be conveyed in plain text form, for example to carry -the list of labels in &xep0128; or a &xep0004; configuration form, the -following algorithm is to be applied:
+the list of labels in &xep0128; or a &xep0004; configuration form, the structure described above is converted to a simple text-based form. + +Each <simple-label/> element is converted to a line of text. The line is composed of the value of the type attribute of the element, followed by a single space character (U+0020), followed by the character data of the element.
Each line in the text-multi field is prefixed with the key of the -corresponding <simple-label/> element. The key is followed by a single -space character (U+0020), followed by the character data of the -<simple-label/> element.
+Each line in the text-multi field corresponds to a converted <simple-label/> element as described above.
