I'm rewriting an old static website and had to implement some contact info. For that I used the <address>
tag, where I saw that you could further annotate an e-mail address by adding mailto:
to the href attribute so that it opens the default mail program and a phone number by adding tel:
, which when clicked prompts the user whether or not they want to call the person (I have my Android synced with Chrome so it asked me if I want to call that number via my Android).
My question is whether there are more of these special href annotations (ex. for opening coords in Google maps)?
