***** NOT A TEACHER *****
I think that most American writing teachers in 2015 tell their students to avoid unnecessary openings such as "I want / wish / would like to bring to your attention that ...."
Students are taught to write tightly. That is, say something and stop.
Dear Mr. Smith:
I have noticed that for the last five days The Parser has been smoking cigarettes and drinking beer in the basement during the lunch hour.
There is no need to say anything else. Mr. Smith knows that such behavior is against company rules and probably against the law. The boss will then take the action that he deems necessary. You have done your part.
You are actually insulting your boss if you tell him that you wish to bring something to his attention. He knows that you wish to being something to his attention, for he is reading a note that you took the trouble to write to him.
