<citationref> (Citation Reference) Description .email comment.
Description
This element contains a reference to a citation from within text. The target element should therefore be one of the following:
-
-
-
-
-
-
-
Here is a typical example:
... from a trajectory analysis (15)
... from a trajectory analysis <citationref linkend="CIT0991">15</citationref> 
Note the missing backets from the tagged example above. Such characters can be added automatically, if required, and their presence or absence will depend as much on the rules for a given journal as for general conventions adopted for a given electronic re-publishing system.
Sometimes, there is a reference to a citation that includes the author name and the date of the publication, as in the following example:
... from a trajectory analysis (Smith, 1991) ...
In this case, the tagging should be:
... from a trajectory analysis (Smith,
<citationref linkend="CIT0991">1991</citationref>) ...
Note the inclusion of both the name, and the brackets, around the reference element. This is the exception to the usual rule that such punctuation should be omitted.
Sometimes, however, there are several references to citations that involve the same author, as in the following examples.
First, there might be two or more dates given separately:
... from a trajectory analysis (Smith, 1991, 1993, 2000)
... from a trajectory analysis (Smith,
<citationref linkend="CIT1991">1991</citationref>
<citationref linkend="CIT1993">1993</citationref>
<citationref linkend="CIT2000">2000</citationref>) ...
Second, there might be a range of dates given (even though there will not be a citation for each of the dates in the range):
... from a trajectory analysis (Smith, 1991 - 2000)
... from a trajectory analysis (Smith,
<refrange text="1991-2000">
  <citationref linkend="CIT1991">1991</citationref>
  <citationref linkend="CIT1993">1993</citationref>
  <citationref linkend="CIT2000">2000</citationref>
</refrange>) ...
Third, there might be multiple citations in the same year, but the year number is not repeated in the text:
... from a trajectory analysis (Smith, 1991a, b)
... from a trajectory analysis (Smith,
<citationref linkend="CIT0001">1991a</citationref>
<citationref linkend="CIT0002">b</citationref>) ...
Finally, there might be a range and individual references to citations in the same year:
... from a trajectory analysis (Smith, 1991a-c, e)
... from a trajectory analysis (Smith,
<refrange text="1991a-c">
  <citationref linkend="CIT0001">1991a</citationref>
  <citationref linkend="CIT0002">1991b</citationref>
  <citationref linkend="CIT0003">1991c</citationref>
</refrange><citationref linkend="CIT0004">e</citationref>) ...
