DDS12 — Unlimited setting for Resource limits not clearly explained

Summary:
In section 2.1.3.19 it is not clear how to specify unlimited resource limits. (It is mentioned in the QoS table in section 2.1.3 that the default setting for resource_limits is length_unlimited, but in the context of 2.1.3.19 this is not repeated).

Proposed Resolution::
Specify in Section 2.1.3.19 that the constant LENGTH_UNLIMITED must be used to specify unlimited resource limits.

Proposed Revised Text::
In section 2.1.3.19 add the following paragraph before the last paragraph in the section (the one that starts with "The setting of RESOURCE_LIMITS …":

The constant LENGTH_UNLIMITED may be used to indicate the absence of a particular limit. For example setting max_samples_per_instance to LENGH_UNLIMITED will cause the middleware to not enforce this particular limit.
