A neat little feature that as far as I can tell is only available in Doom Emacs is the ability to link to specific labeled lines from different org files. So for instance when I use org-roam I can in an org file with ID foo label a block of code with #+name: my_code and then from a different org file write a link like [[foo::my_code][Some code]] and have it refer back to the exact line in the first file.

I have several questions:

1. Is this feature indeed specific to Doom Emacs? Looking at the code that gets called it seems there were modifications in Doom to org-id that allow appending a name to an org ID using double colons in this way. I’ve asked in a number of other forums and no one has been able to replicate this outside Doom.

3. Connected to this: if I export an org file containing an ordinary link to another node to PDF, the PDF compiles and I get a dead link in the file. If one tries to export org files with these double colon links there's an error message `Unable to resolve ID "foo::myname"`. Is there a way to generate the PDF just like in the first case?

Thanks,
