-But Guile, like most Scheme implementations, also goes beyond R5RS in
-many ways, because R5RS does not give specifications (or even
-recommendations) regarding many issues that are important in practical
-programming. Some of the areas where Guile extends R5RS are:
+Guile complies fully with R5RS (@pxref{Top,
+,Introduction,r5rs,R5RS}), and implements some aspects of R6RS.

+Guile also has many extensions that go beyond these reports. Some of
+the areas where Guile extends R5RS are:
