Many Wikipedia articles have inline citations like this one:
Honey gets its sweetness from the monosaccharides fructose and glucose, and has about the same relative sweetness as granulated sugar. It has attractive chemical properties for baking and a distinctive flavor that leads some people to prefer it to sugar and other sweeteners.
I am using articles from Wikipedia in my book and I have already provided credit to the authors by including URLs of the articles. Can I remove these numbers that refer to footnotes? They already exist in the Wikipedia pages and a reader can see the reference on the site itself if he wants. Wikipedia attribution policy (Reusing Wikipedia content) says that some external notations should generally be preserved by the re-user. "Should be" doesn't mean "must be", does it?
