Add to author response content more sample data.

[gnott]

Regarding issue https://github.com/elifesciences/XML-mapping/issues/88, I wanted to add some more types of content that may appear in a decision letter or author response.

I was happy to find many of the content types were already represented in the kitchen sink XML.

Here I'm suggesting to add some additional content to the author response that I didn't see was represented in any <sub-article>:

• <disp-formula>
• unicode character: ϕ
• <list> with a nested <list>, with @list-type of order and roman-lower (ones I've observed in samples so far)
• apostrophe character '
• <sub>
• <sup>
• escaped ampersand &
• unmatched angle bracket <
• <italic>

How these are represented is up to revising and suggestions. This may inform how a decision letter parser library XML output sample may look, which may be loosely based on this kitchen sink XML.

@FAtherden-eLife can you review and merge this?

Thanks!

Changes made in this look fine. Holding merging pending discussion in https://github.com/elifesciences/XML-mapping/issues/89, as it might be worth adding the @ids before merging.

[Melissa37]

Agree - suggest adding IDs to equations too then merge

Finished a couple more commits. The first, where I neglected to add @id to the <disp-formula> I added to the author response, the values are now present. The second, I added an @id to the <mml:math> tags that are inside <inline-formula> tags.

I can leave this PR open for another check before merging, @Melissa37 or @FAtherden-eLife if you please - thank-you!

Looks good - thanks @gnott.
