Hello, I cannot find any valid info (reference) about use of the command \definestructureconversionset. I just have some examples. Could anyone explain how these commands should work? \definestructureconversionset[name-of-conversion-set][par1,par2,...][Par1,Par2,...] \definestructureconversionset[name-of-conversion-set][][Par1,Par2,...] % 1St par. set empty \definestructureconversionset[name-of-conversion-set][par1,par2,...][] % 2Nd par. set empty \definestructureconversionset[name-of-conversion-set][par1,par2,...] % 2Nd argument omitted TIA.
