ZF-11900: Zend_Validate_Hostname::ALLOW_ALL does not match documentation
The manual for Zend_Validate_Hostname says: "For security reasons ALLOW_URI is not contained within ALLOW_ALL." This is not true: ALLOW_ALL is 15, which does contain ALLOW_URI (8). Additionally, the Docstring for both constants says the same: "Allows all types of hostnames".
Either the documentation is incorrect ot ALLOW_ALL should be set to 7 to match the documented behavior.
