DDS11 — TransportPriority QoS range does not specify high/low priority values

The specification does not state what the valid range of the transport priority values is, now does it state whether higher or lower values correspond to higher priorities.

Proposed Resolution:
Stipulate that the range of TransportPriorityQosPolicy::value is the entire range of a 32 bit signed integer. Larger numbers indicate higher priority. However, the precise interpretation of the value chosen is transport- and implementation-dependent.

Proposed Revised Text:
The second paragraph of section 2.1.3.14 contains the sentence:
"As this is specific to each transport it is not possible to define the behavior generically."

This sentence should be rewritten as follows:
"Any value within the range of a 32-bit signed integer may be chosen; higher values indicate higher priority. However, any further interpretation of this policy is specific to a particular transport and a particular implementation of the Service. For example, a particular transport is permitted to treat a range of priority values as equivalent to one another."
