The following code, in a metadata.xml, should show a calendar in the directive field, but it isn't:

    <INPUT>
      <NAME>TEST</NAME>
      <DESCRIPTION>We should have a calendar</DESCRIPTION>
      <CONSTRAINT>
        <TYPE>datetime</TYPE>
      </CONSTRAINT>
    </INPUT>

Content is properly validated, if it's not the proper date, we have the error message

Wrong value hft for field 'We should have a calendar': expecting a datetime in ISO 8601 standard.

a calendar would really help to follow the proper format
