subjectRelTable
The <subjectRelTable> element is a specialized relationship table which establishes relationships between the subjects in different columns of the same row. This element provides an efficient way to author non-hierarchical relationships between subjects. Tools (such as search tools) that use subject relationships to find related content may use these associative relationships in a similar way to the hierarchical relationships.

Example 173. Example
The subject relationship table in this example establishes environmentFor relationships between operating systems and applications. Based on the subjectRole element, subjects in the first column are operating systems which are the environment for an application, while subjects in the second column are applications that run in that environment. For a user interested in content about the operating system, content about the applications may also be relevant.
