[jats-list] Third-party author profiles

[Alf Eaton <eaton.alf@xxxxxxxxx>]

If an author of an article has added information to their manuscript
about their profile information on third-party sites (e.g. Twitter),
would this be an appropriate way to mark it up?:

<contrib id="author-1" contrib-type="author" corresp="yes">
  <name>
    <surname>Surname</surname>
    <given-names>Given Name</given-names>
  </name>
  <xref ref-type="aff" rid="aff-1">1</xref>
  <email>example@xxxxxxxxx</email>
  <ext-link ext-link-type="twitter-username"
xlink:href="https://twitter.com/examplename";>ExampleName</ext-link>
</contrib>

It seems right, but I'm not sure what a good value for @ext-link-type
would be - is there any precedence for something similar?

Thanks,
Alf
