How do I refer to my PhD studies in my CV; under education or experience? I am currently updating my CV before applying for postdoc positions (and grants) and got a bit puzzled about a small but possibly important detail.

The chapters I have on my CV are Education, Experience, Extracurricular/Voluntary Work and Publications. While I am not forced to keep this structure, I find it very logical and rather neat, so unless there is a good reason to do so I will probably keep the structure. 

Now, to the question, I am not sure if I should include my PhD years under education or under experience. Not sure if it's the same elsewhere but over here in Sweden, the years as PhD student counts as both education and full-time employment. I think there are points to both sides of the coin.

The work I have done as a PhD student is quite relevant for the type of stuff I will be applying to hence an argument for listing under work experience. Besides I am not too happy about the last entry in my "Experience" section to be from 4 years ago, as it stands looks a bit like I am "fresh off the school". 

Is there a generally accepted way to tackle that?
I put it in both places. Under Education I list my time as a graduate student, and under Experience (as "Appointments"), I list my time as a Graduate Research Assistant. I've seen this on lots of CVs in the US. Both are true, and both convey the right meaning.
