In the current Parsoid integration (through the PHP parser) of the Citation extensions, its references are zero-indexed rather than one-indexed in target names - this means that the generated HTML from Parsoid looks (roughly) like:
<li id="cite_note-Foo-0" data-parsoid="…"><a href="#cite_ref-Foo-0-0" data-parsoid="…">↑</a>…</li>
... rather than:
<li id="cite_note-Foo-1"><a href="#cite_ref-Foo-1-0">↑</a>…</li>
