content_view.pt looks like:

then when creating content type view just use BrowserContentView instead of BrowserView. until i take some time and write nice product for plone so you could easily use this peace of code you must register content provider in zcml by hand (browser/configure.zcml)

sorry about small pictures blogger does not provide some nice way to paste some code to you so i need to show you with pictures. i have my personal blog page in preparation, so during this summer i'll move my blog (it will be plone ofcourse :) )
