Help:References
Learning about refs and footnotes. The full help is in Wikipedia's help.
Here are some refs using the group attribute.[a 1][a 2] And another that doesn't.[1]. Now we call {{reflist}} with the group attribute set.
Using group is the way to handle footnotes for multiple tables, for example.
And here are some more references without a group attribute.[2][3] We can't access the first group now, because it's already been listed.[a 1]
A section
You can also have a mini-list if you use LDR: list-defined references, by adding a group attribute again[z 1] And a second.[z 2] Note that the group does not appear in the reference list below, so that could be confusing.
You can also do this again, with the same or different ref names.[z 1] And a second.[z 2] Not recommended though.
Another section
This section uses EFN.[a] And another.[b] You can only have one section like this. So, for example, if there are several tables, you can't use {{efn}} to give them each footnotes.
References
These are all the ones that haven't already been listed with either {{notelist}} or {{reflist}} + group.
