Zend Framework Manual is for 1.5PR not 1.0.3
Note that the online manual is for version 1.5PR, not 1.0.3. This is important as the new 1.5 features are now documented, but won’t work if you are using the 1.0.3 stable version of the Framework.
Also, as a side note, be aware that Zend_Loader is much slower in the 1.5PR release compared to 1.0.3, so don’t use it on a high traffic site! This issue has been fixed on the trunk (revision 7726), so if this issue is affecting you the give a snapshot a try and see if it solves it.
