if there’s a document.doctype, looks like you probably also want to check that document.doctype.name is 'html'?

For this you’re going to need a gatherer and an audit. Generally the gatherer will collect the information on the doctype from the browser and the audit will do the actual correctness testing. hreflang is a pretty complicated audit compared to this 😃 so a better example might be the meta-description audit.

The PR for that audit (#3227) lays out pretty well how to get a gatherer and audit to work together, how to add to them to a config, unit tests needed, etc (though most of the SEO category stuff won’t be necessary…it would just go into Best Practices in the default config).

Let us know how things go!

@schalkneethling I have not implemented an audit for lighthouse yet, just a minor contribution. Would have to dig deep into this one as well, you’ve been first to answer this open issue.

I think thats more a question to regular contributors/maintainers if they assist you in a WIP PR.
