One thing I stumbled upon while going through the RFC a last time is the expected result of the hosttype detectiopn on mailto-URLs.

I couldn't find anything about the reasoning in the RFC or in the linked internals-discussion thread why

$url = new Uri\WhatWg\Url("mailto:john.doe@example.com");
echo $url->getHostType();

will be `null` and not `UriHostType::RegisteredName`

I might have missed something so please either shed some light on that or point me to the relevant discussion/documentation.

Thanks!

Cheers

Andreas

Hi Andreas,

The mailto URL scheme does not have any host component as per. its different RFCs
it is composed of:

  • a scheme component : mailto
  • a path component containing a list of email addresses separated by commas (as per your example)
  • and a query component representing the email optional headers info

As such the WHATWG and the RFC3986 interpretation will all return null because there’s simply no host to describe.
