biblioentry for an encyclopedia article

What is the proper way to markup a bibliography entry for an
encyclopedia article? Should I just make the <biblioentry> for an
encyclopedia and then mention the article name in my body text? I am
only going to use this one article from the encyclopedia. If it
matters, the article is on Wikipedia. (Please spare me the lecture on
tertiary sources. I want to mention a specific feature of the article
itself.)
