+(e.g. Etags and Eglot) and have the results all at once.
+
+To enable, toggle the @code{xref-union-mode} minor mode.  If you want to
+exclude certain modes, take a look at the user option
+`xref-union-excluded-backends'.
+
+You can also manually make use of @code{xref-union} by adding an object
+of the form @code{(union XREF-BACKEND-1 XREF-BACKEND-2 ...)} to
+@code{xref-backend-functions}.")
