Is that "rule" specified in the doc explicitly anywhere?

I have patterns in the SHARC DSP port that are "selected"
by the single conditional-expression, e.g., something like

	(define_insn
  	 [RTL]
	"am_I_true (...)"
	"insn-code"
	)

	(define_insn
	[RTL]
	"!am_I_true (...)"
	"insn-code"
	)

Is this okay?
