Comment:

 Hi Isis. As I've mentioned a few times on irc unsanitized bridge
 descriptors are simply normal relay descriptors. As such you can simply
 use the **RelayDescriptor** and **RelayExtraInfoDescriptor** classes. The
 BridgeDescriptor and BridgeExtraInfoDescriptor are for **sanitized bridge
 descriptors**

 On a side note calling raw constructors like that is not the advised way
 of using Stem. Also, the '@type bridge-extrainfo' annotation does not
 exist. If you meant '@bridge-extra-info 1.1' then that is an annotation
 specifically for **sanitized** extrainfo bridge descriptors.
