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}}.
|
The author metadata is in the rft.aulast field. In this case, it is percent-encoded and is rendered as <span class="smallcaps" style="font-variant:small-caps;">Sam Drucker</span>
Reference management software will interpret the entire span as the author name.
