How to use the @vue/compiler-core.Namespaces.HTML function in @vue/compiler-core

import {
  TextModes,
  ParserOptions,
  ElementNode,
  Namespaces,
  NodeTypes
} from '@vue/compiler-core'
import { makeMap, isVoidTag, isHTMLTag, isSVGTag } from '@vue/shared'

const isRawTextContainer = /*#__PURE__*/ makeMap(
  'style,iframe,script,noscript',
  true
)

export const enum DOMNamespaces {
  HTML = Namespaces.HTML,
  SVG,
  MATH_ML
}

export const parserOptionsMinimal: ParserOptions = {
  isVoidTag,
  isNativeTag: tag => isHTMLTag(tag) || isSVGTag(tag),
  isPreTag: tag => tag === 'pre',

  // https://html.spec.whatwg.org/multipage/parsing.html#tree-construction-dispatcher
  getNamespace(tag: string, parent: ElementNode | undefined): DOMNamespaces {
    let ns = parent ? parent.ns : DOMNamespaces.HTML

    if (parent && ns === DOMNamespaces.MATH_ML) {
      if (parent.tag === 'annotation-xml') {
        if (tag === 'svg') {
