Framework under source control and repository structure

How do you think it is necessary to control framework by version control system or just an application. What do you think about the best way to organise directories in subversion repository? What structure of repository do you use and for what kind of applications? that’s what Yii uses.

For any subversioned application, I recommend just to follow the recommended standard and create tags, branches and trunk directories. If you want to include the framework, use an external reference.
