When checking a site I am working on for broken links, I found this:
<a href="x-apple-data-detectors://6">.</a>I tried googling, but all I can find about it seem to be about this form:
<a href="#" x-apple-data-detectors="false">What is the intention when this appears in a href?

What is the intention when this appears in a href?
No intention. It's just broken.
The x-apple-data-detectors URI scheme is used internally by some Apple applications on iOS and macOS to automatically insert clickable links for certain types of information (like phone numbers, dates, and locations). These links have no meaning outside this context; this one probably slipped in by mistake.
