That commit creates some artifical parameter called 'first' that you can use as value in param_attribute. For example: <option type="from_param" name="singlePaired.mate_list" param_attribute="first.input_mate1.ext" /> I use that to retrive the filetype of paired end reads that are inserted in a repeat tag. Assuming that every mate pair is from the same type as the first element.
