I would like some clarification on the user of XREF in ACEDB.
For example,

?Author   Name Text
          Paper ?Paper

?Paper    Title Text
          Author ?Author

The example above should create a 2-way link between Author and paper.
However the syntactic definitions for ACEDB (Dec. 10 1992) gives an
example (edited here for brevity) that reads

?Author   Name Text
          Paper ?Paper XREF Author

?Paper    Title Text
          Author ?Author XREF Paper

What does the XREF accomplish? What can you do that would otherwise
be impossible without the XREF? Can someone illustrate this point
with an example?
