[E] Notes At this point the author would like to interrupt this list to indicate a possible application of the value attribute found in Template:Cnote2 . Very long lists similar to this one may benefited by having it be broken down. Remember to remove the link to an inline occurrence, giving the feel of an regular list, set n=0.
