But actually I strongly suspect that this is dead
code.

[AquaA11yTextWrapper rTFForRangeAttributeForElement:forParameter:] is
called only from [AquaA11yWrapper rTFForRangeAttributeForParameter:],
and that is not called from our code, nor do I see any mention of
either rTFForRangeAttributeForElement or
rTFForRangeAttributeForParameter in documentation or when googling.

The NSView documentation does talk about accessibilityRTFForRange,
though. Could this be some copy/paste error since initial commit, code
that has never been tested? Would not surprise me a bit.
