Allow break in tables

[fred-atherden]

The JATS element <break/> is used to indicate a line break. We (eLife) need to be able to use this element within tables (most often in <td/> elements, but could also be needed in th elements) so that renderers can output breaks.

Example of it's use:

<table-wrap id="table1" position="float">
          <object-id pub-id-type="doi">10.7554/eLife.43788.003</object-id>
          <label>Table 1.</label>
          <caption>
            <title>Data collection and refinement statistics</title>
          </caption>
          <table frame="hsides" rules="groups">
            <thead>
              <tr>
                <th colspan="2" valign="top">Protein:RNA</th>
                <th valign="top">PUF-8: <break/>PBE</th>
                <th valign="top">FBF-2 SS/Y: <break/>PBE</th>
                <th valign="top">FBF-2 AS/Y: <break/>PBE</th>
                <th valign="top">FBF-2 AQ/Y: PBE</th>

Currently break is not allowed in the texture schema:

[obuchtala]

This has been prepared in #1231 and only needs to be activated by allowing for <break> in <td> and <th> in TextureJATS.

@Melissa37 this is an example of a 'micro' task which we could address without a complex requirements engineering process. I'd like to label such issues and treat them as general backlog similar to bug fixes but with less prio. E.g. @Integral could work on such things while we are spec'ing out the more complex requests. What do you think?

[michael]

How about a label "backlog" for those?

[Melissa37]

Hi there

@FAtherden-eLife can you add this requirement to our new Tables feature request ticket when we get to it perhaps?

@michael I'd be happier to close this and wrap it up in a new feature request than create a new label for it as it's an eLife requirement to go live and needs a proposal.

Cheers
