 * The Data representation in SDP PDUs (pps 339, 340 of BT SDP Spec)
 * These are the exact data type+size descriptor values
 * that go into the PDU buffer.
 *
 * The datatype (leading 5bits) + size descriptor (last 3 bits)
 * is 8 bits. The size descriptor is critical to extract the
 * right number of bytes for the data value from the PDU.
 *
 * For most basic types, the datatype+size descriptor is
 * straightforward. However for constructed types and strings,
 * the size of the data is in the next "n" bytes following the
 * 8 bits (datatype+size) descriptor. Exactly what the "n" is
 * specified in the 3 bits of the data size descriptor.
 *
 * TextString and URLString can be of size 2^{8, 16, 32} bytes
 * DataSequence and DataSequenceAlternates can be of size 2^{8, 16, 32}
 * The size are computed post-facto in the API and are not known apriori
