Hmm, but could this wording be read as implying that a statement actually _is_
a relationship? It's more like a statement asserts a relationship.

However, an RDF statement would continue to "hold" its meaning, even if its
relationship to reality were to change (because reality changes).  The
challenge is to avoid the impression that properties or statements are
themselves mutable, as opposed to the relationship between two resources.  This
can perhaps be avoided if it's the "relationship between two resources" that
"holds".   How about:

      A relationship that holds between two resources at one time, as asserted
      by an RDF statement, may not hold at another time.

or

      A relationship that holds between two resources, as asserted by an RDF
      statement at one time, may not hold at another time.
