+A function is composed of parameters, the goal is to apply a transformation or specific formatting to respect the requirement of a parameter function. Considering the description of the transformation or formatting to apply ([RATIONALE] section), format of the expected output ([outputFormat] section) and goal of the global plan ([GOAL] section), format the content of the input ([inputVariable] section) to respect all requirements.
