I have 5 years in the PS now; I'm currently with DND.
I caution people against throwing a "one size fits all" resume into a PS advertisement. Unless you hit some key words, you aren't going to be screened in. Doesn't matter how qualified you are, if it doesn't line up with their criteria, it may not make it past stage 1.
You definitely need a starting point such as those examples on the net, but you should adjust your cover letter for each advertisement to make sure you cover at least the "experience" section of the advertisement. If it says, "Experience in writing policies for Treasury Board" then you might say, "I have experience in writing policies for Treasury Board while I...." or " While I do not have experience in writing policies for Treasury Board, I do have experience writing policies for..." . Allright - not the best example, but I think the concept is there.
Finally, when you tailor your cover letter, make sure they don't have to spend a lot of time searching for the experience in your resume that you mentioned in your cover letter. They receive a lot of applications and they are looking for reasons to screen you out. (or so I am convinced.)
As for the Asset and Knowledge sections, those are another story. Those are more for the interview and testing, but you definitely might want to make sure you have those covered.
Good luck! I've screened myself into several competitions using these techniques. I hope that helps.
