<subjectRole>
The <subjectRole>
element, when used within a
<subjectRel>

other subjects in the same row of the current <subjectRelTable>
. By
default, no relationship is defined between multiple subjects in the same
<subjectRole>
element. When used within the
<subjectRelHeader>
, the <subjectRole>
element
defines the category of subject or relationship provided by that column.
