* 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
