Now to R6RS. Section 6.4 says that auxiliary syntax describes a syntax binding. Section 12.4 of the R6RS Library Report defines `...' as auxiliary syntax. The example definition of `case' in Section 12.5 ibid. shows explicitely that auxiliary keywords are matched using `free-identifier=?' (in this example, `else'). Also, in all other regards with respect to auxiliary syntax R6RS does not differ from R7RS.
