It is hyperbole that the 4.x TCL content repository is so flawed
You are absolutely right. However, given that no one here has claimed that the content repository is "so flawed", this is a red herring.
Are you by any chance confusing the content repository with the content management system, which is one of several *clients* of the content repository, not the content repository itself?
Or did you not notice that this forum's the OpenACS CMS (Content Management System) forum?
Whatever...
