Summary: When I subscribed to the docset feeds and downloaded the updates in Xcode, all of the documentation files were put under quarantine. Thus, any time I select "Open Page in Browser" from a doc page in Xcode, I get a warning that the doc page "is a web application which was downloaded from the internet". This makes the "Open Page in Browser" command really annoying and useless. Steps to Reproduce: 1. Clean install Mac OS X 10.5.5. 2. Clean install Xcode 3.1.1. 3. Launch Xcode. 4. Select Documentation from the Help menu. 5. Subscribe to the Core Library and Developer Tools Library docset feeds. 6. Download the updated docsets. 7. In the Xcode documentation window, navigate to any page in the docsets. 8. Bring up the contextual menu, and select "Open Page in Browser" Expected Results: The page opens in Safari without warning. Actual Results: Every time, I get a warning. See the attached screenshot "quarantine.png". This occurs even when I open the same page subsequent times using "Open Page in Browser". Regression: No regression testing done. Notes: If I launch Terminal and do "ls -@lR /Developer/Documentation/DocSets/com.apple.ADC_Reference_Library.CoreReference.docset", I can see that all of the files have the extended attribute "com.apple.quarantine".
