why?

[Joao da Silva, 2014/03/04 23:18:01]

Because that's supported in CFDictionaries but not in base::DictionaryValues.

The Chrome app manifest (which declares the supported managed settings on Mac)
restricts the keys to strings, so no valid policy configuration will have
anything other than strings as keys.

+// Returns NULL if an invalid CFType was found, such as CFDate or CFData.
+// NSDictionary is toll-free bridged to CFDictionaryRef, which is a
+// CFPropertyListRef, so it can also be passed directly here. Same for the
+// other NS* classes that map to CF* properties.
+POLICY_EXPORT scoped_ptr<base::Value> PropertyToValue(
+    CFPropertyListRef property);
