PlaceHolder Map
I'm preparing to deliver a WCM developer class internally. While preparing, I have decided to map out some of the placeholders to give students a better understanding of how 30 over placeholders are used. So here it is, for general public consumption.

(Screenshot taken by SnagIt)
PlaceHolderPageTitleinTitleArea is below PlaceHolderTitleBreadCrumb
PlaceHOlderTitleAreaSeperator is above PlaceHolderLeftNavBar
PlaceHolderPageDescription is above PlaceHolderMain
PlaceHolderFormDigest, PlaceHolderUtilityContent, PlaceHolderBodyAreaClass, PlaceHolderTitleAreaClass is at the bottom of the page
