Unique identifier of the issue the document belongs to.

The element must have the attribute ``@pub-id-type``, which is used to identify the type of the identifier.

The attribute ``@pub-id-type`` allows the use of some values, see :term:`NISO JATS Journal Archiving DTD` for these values.

As best practice :term:`Érudit PS` requests the use of at least one of the following values:
