<!-- Maintenance updates to version 3.3:

     - volumeno, issueno are now optional in journalcit
     - pubplace, editor have been defined
     - citpub has been introduced to avoid the org nesting required by
       publisher
     - section has been introduced as an optional extra in the backmatter
       (with type - so it can be used for corrigenda)
     - emphasis elements have been added to the content model of citation

     plus a note on usage - we will use <date role="accepted"> instead of
     creating a new element

<!--         XML/SGML CONFORMANCE     -->
<!-- ================================ -->

<!-- By default the DTD is XML conformant, which means that it cannot contain
     tag omission indicators.  This is indicated by setting the parameter entity
     DTD-IS-XML to the value "INCLUDE", which in turn causes the parameter entity
     DTD-IS-SGML to have the value "IGNORE".  This setting can be overridden by
     setting DTD-IS-XML to "IGNORE" in the document's internal subset.

     The principal effect of this XML option is to remove the tag omission
     indicators from element declarations.

       - title should use the type attribute to distinguish non-italic (descriptive) titles;
       - biblscope should contain 'simple text' to allow e.g. italic within it.
