According to e2fsprogs-1.41.12 source, in lib/e2p/pf.c , it's

 "s", "Secure_Deletion"
 "u" , "Undelete"
 "S", "Synchronous_Updates"
 "D", "Synchronous_Directory_Updates"
 "i", "Immutable"
 "a", "Append_Only"
 "d", "No_Dump"
 "A", "No_Atime"
 "c", "Compression_Requested"
 "B", "Compressed_File"
 "Z", "Compressed_Dirty_File"
 "X", "Compression_Raw_Access"
 "E", "Compression_Error"
 "j", "Journaled_Data"
 "I", "Indexed_directory"
 "t", "No_Tailmerging"
 "T", "Top_of_Directory_Hierarchies"
 "e", "Extents"
 "h", "Huge_file"

...which is 19, but I don't think all of these are used.  The compression,
secure deletion, and undelete attrs have "these things are currently not
really implemented" warnings on them in the official documentation and so
forth.
