Explain COinS issues

Citation templates such as Citation Style 1 and Citation Style 2 generate COinS metadata. If a template is used in a citation template field, then it may inject HTML into the metadata.

Compare the rendered HTML for {{cite book}} with |author= using no template and using {{smallcaps}}.
