I often use the AttributeSplitter or other transformers to parse data and rename the resulting list elements as regular attributes.
In FME 2015, an AttributeRenamer could point to a specific list element (ie _list{1}) to rename it, this is no longer the case in FME2016.
Example
_list{0}: 45
_list{1}: 30
_list{2}: 31
would be renamed to
Degrees: 45
Minutes: 30
Seconds: 31
