[jats-list] Primary and Secondary MSC tagging

["franziska.buehring@xxxxxxxxxxxxx" <jats-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Dear all,

when we have Classification Codes as follows:

Mathematics Subject Classification 2010
Primary: 00A09; Secondary: 26A33, 35R11

Are there any recommendations how to tag this?

I would go within <nested-kwd> as this is the only way to have a hierarchy:
<kwd-group kwd-group-type="MSC">
  <title>Mathematics Subject Classification 2010</title>
  <nested-kwd>
    <kwd>00A09</kwd>
    <nested-kwd>
       <kwd>26A33</kwd>
       <kwd>35R11</kwd>
    </nested-kwd>
  </nested-kwd>
</kwd-group>

But then I am missing the terms "Primary" and "Secondary", which might now
always be obvious. So, ideally, there should be something like nested
kwd-groups:

<kwd-group kwd-group-type="MSC">
  <title>Mathematics Subject Classification 2010</title>
  <kwd-group kwd-group-type="MSC">
    <title>Primary</title>
    <kwd>00A09</kwd>
    <kwd-group kwd-group-type="MSC">
      <title>Secondary</title>
       <kwd>26A33</kwd>
       <kwd>35R11</kwd>
    </kwd-group>
  </kwd-group>
</kwd-group>
(or something similar to that...)

How do you handle this?

Best, Franziska
