Is this still needed? :(

Yes, although we are not using type map, we still need this for base::ListValue.

"should pay extra attention" how? Just checking that the depth never exceeds 32?

[Miao, 2016/09/07 17:58:30]

Replaced that sentence with
"Note BluetoothSdpAttribute supports up to depth 32 for the attribute with
multi-layer sequences. The attributes within a sequence which has the depth
beyond the maximum supported depth will be invalidated and ignored."

The callers should be aware of the fact that we only support up to the depth 32
when they construct a BluetoothSdpAttribute.
