Descargar el XML Facturae actual o conservado

Devuelve como flujo el XML Facturae 3.2.2 de una factura emitida: .xsig firmado si hay certificado de firma; si no, .xml (consulta X-Facturae-Signed). - Sin submission_id exporta la fuente legal actual; las facturas en borrador y programadas devuelven 422 invoice_not_emittable_for_facturae. - Con un submission_id propio devuelve los bytes conservados exactos de ese intento, nunca regenerados ni completados con datos en vivo. - El hash y el ETag solo acompañan a un artefacto conservado conocido.
