It's akin to asking what values could revert-buffer-function have: 
different ones. Every command that uses the xref UI is responsible for 
creating such a function (though most of current ones have a common 
implementation only parameterized by KIND, see xref--create-fetcher).

I have added some more docstrings and a comment, though. Hope they clear 
up a few things.
