Improvement : Add an "additionalInfo" tag if data is intended to be updated annually

[yvanlebras]

Using this kind of tag on the EML file:

  <additionalInfo>
    <para>This data set is intended to be updated annually.</para>
  </additionalInfo>

Can be something of interest for EAL @clnsmth ? and a "box" to select on MetaShARK maybe @earnaud ?

Thanks, @yvanlebras. Another good place for this info is /eml/dataset/maintenance (see EDI data package best practices, and EML schema). EAL supports this via make_eml(..., maintenance.description). Note, this only covers maintenance/description but could be extended to maintenance/maintenanceUpdateFrequency and maintenance/changeHistory.
