Does the Mobius use XSD? If it uses where is the version specified, also since the version of XSD is changing in time how is it handling that version change?

I checked that the mobius uses oneM2M standards and dynamically uses the version specified here is that right?
var xml = xmlbuilder.create(‘m2m:’ + rootnm, {version: ‘1.0’, encoding: ‘UTF-8’, standalone: true},
{pubID: null, sysID: null}, {allowSurrogateChars: false, skipNullAttributes: false, headless: false, ignoreDecorators: false, stringify: {}}
