I understand that English is not your native language. I think The problem is that you don't know what "attribution" means. There are multiple attributions, per the policy regarding "in text attributions." 

"The Swiss German physician and alchemist Paracelsus"

"The French pseudo-novel Comte de Gabalis"

"In Rape of the Lock (1711)"

"in Shakespeare's The Tempest."

" in Terry Brooks' Magic Kingdom of Landover series"

"Do not add this template...

In articles containing a list of sources at the end, but no inline citations, including parenthetical references or in-text attributions, consider {{no footnotes}} when the article would be significantly improved by detailed attribution of sources to specific claims."
