Element or context:
<pub-date>, <pub-history>, <event>, <event-desc>
Requirements:
- Include the 'iso-8601-date' attribute on <date> and <pub-date>
- Pub dates: Contain the pub date (date the article was published on the web) within <pub-date>. Use attribute publication-format="electronic" and attribute date-type="pub" (not: "epub")

This will not necessarily be the same as the first date the article went online (if there is an Accepted manuscript online date for the article).

- Set the contents of <event-desc> according to the table below
| Event type (<event-desc>) | @event-type code |
|---|---|
| Received | "received" |
