     <p>The <directive>SetEnvIfExpr</directive> directive defines
-    environment variables based on an <directive module="core" type="section">If</directive>
-    <code>ap_expr</code>. These expressions will be evaluated at runtime,
+    environment variables based on an <a href="../expr.html">expression</a>.
+    These expressions will be evaluated at runtime,
     and applied <em>env-variable</em> in the same fashion as <directive
-    >SetEnvIf</directive>.</p>
