OpenLayers 4.x DescribeFeatureType to populate a filter menu

Question

With OpenLayers 4, I'm trying to get field names from a WFS request (https://localhost:8080/myws?SERVICE=WFS&REQUEST=DescribeFeatureType&VERSION=2.0.0&TYPENAME=ms:layername&outputFormat=gml/2.1.2) and parse it into JSON or something else.

I found a solution, but it is for OpenLayers 2 (example)

Does somebody know if

OpenLayers.Format.WFSDescribeFeatureType();

will be deployed into OpenLayers 4?

Any other way possible? My goal is to "harvest" my WFS DescribeFeatureType to populate a filtering menu.

Look at jsonix [1] and w3c-schemas [2] instead

import {XSD_1_0} from 'w3c-schemas/lib/XSD_1_0';
const xsdContext = new Jsonix.Context([XSD_1_0]);
const xsdUnmarshaller = xsdContext.createUnmarshaller();
var schema = xsdUnmarshaller.unmarshalString(xmlhttp.responseText).value;
var element = schema.complexType[0].complexContent.extension.sequence.element;
