TypeScript type error for changefreq property

[colinhemphill]

There seems to be an issue with the enums for changefreq when using TypeScript. Using an example from the documentation:

var sitemap = smGenerator.createSitemap({
    urls: [
      {
        url: 'http://mobile.test.com/page-1/',
        changefreq: 'weekly',
        priority: 0.3,
        mobile: true,
      },
    ],
    xslUrl: 'sitemap.xsl',
  });

I get the following error:

Type '{ url: string; changefreq: string; priority: number; mobile: boolean; }' is not assignable to type 'string | SitemapItemOptions'.
  Type '{ url: string; changefreq: string; priority: number; mobile: boolean; }' is not assignable to type 'SitemapItemOptions'.
    Types of property 'changefreq' are incompatible.
      Type 'string' is not assignable to type 'EnumChangefreq'.ts(2322)

Yeah, not sure how I should
document TS only stuff. Import EnumChangefreq and assign EnumChangefreq.WEEKLY.
