>> Description:
>> DPWS could specify a stronger constraint than 64kbytes for datagram
>> size: as a UDP datagram must be read in one chunk (unlike TCP
>> streams), supporting SOAP-over-UDP means that a device should be
>> prepared to read any datagram (up to 64 kbytes), which is not always
>> possible in memory-constrained environments (we typically use buffers
>> of a few kbytes). R0029 partially addresses this issue for a different
>> reason (reliability), but it is only a SHOULD (with a limit, the MTU,
>> which is actually probably too low as an absolute constraint) and only
>> for messages sent by services (and not by clients). R0003 also add a
>> constraint, but it is too high (32 kbytes) for our purpose and not
>> specific to UDP messages.
>>
>> Proposed resolution:
>> Proposed max size of UDP messages that MUST be supported by all
>> devices: 4k
