* The Data representation in SDP PDUs (pps 339, 340 of BT SDP Spec)
329
* These are the exact data type+size descriptor values
330
* that go into the PDU buffer.
332
* The datatype (leading 5bits) + size descriptor (last 3 bits)
333
* is 8 bits. The size descriptor is critical to extract the
334
* right number of bytes for the data value from the PDU.
336
* For most basic types, the datatype+size descriptor is
337
* straightforward. However for constructed types and strings,
338
* the size of the data is in the next "n" bytes following the
339
* 8 bits (datatype+size) descriptor. Exactly what the "n" is
340
* specified in the 3 bits of the data size descriptor.
342
* TextString and URLString can be of size 2^{8, 16, 32} bytes
343
* DataSequence and DataSequenceAlternates can be of size 2^{8, 16, 32}
344
* The size are computed post-facto in the API and are not known apriori
