Is the `position` property dropped in CSS 3?

I contacted the support of a mayor IDE, after the CSS property position didn't "auto-complete" in the latest version. They said it doesn't exist in CSS 3. I did some digging, and replied

"CSS Level 3 builds on CSS Level 2 module by module, using the CSS2.1 specification as its core. Each module adds functionality and/or replaces part of the CSS2.1 specification." http://www.w3.org/TR/2011/NOTE-css-2010-20110512/#css3

Additionally, this defines the position property, although it's not finished: http://www.w3.org/Style/CSS/specs#positioning

But they stood their ground. This is a reply from 开发者_开发问答them, after a length debate.

[..] there are indeed many properties in CSS3 which are copied 1:1 from CSS2.1. Among new properties introduced in CSS3, you can find many CSS 2.1 definitions in CSS3 draft. Unfortunately, it's not the case with position and some other properties [..]

I have no grudge towards them, but am curious. Does position really not exist in CSS 3?

While it may not exist in the new Spec (which is TBD), it remains valid.

I ran this through the validator at CSS3 level and it was all good

.jason{
    position:absolute;
}

I don't think so. Look at this Quick Reference Guide compiled by Chris Hanscom. You'll find the positioning spec at the bottom of the right hand column on the second page

Although from last year, the snapshot of css3 state contains position poperty. As stated before, it is the same well know position that in css 2.1. As far as I know css3 doesn't "forbid" anything introduced in previous versions.
