 &lt;p&gt;This element specifies the size of DDSI sample fragments generated by Cyclone DDS. Samples larger than FragmentSize are fragmented into fragments of FragmentSize bytes each, except the last one, which may be smaller. The DDSI spec mandates a minimum fragment size of 1025 bytes, but Cyclone DDS will do whatever size is requested, accepting fragments of which the size is at least the minimum of 1025 and FragmentSize.&lt;/p&gt;
 &lt;p&gt;The unit must be specified explicitly. Recognised units: B (bytes), kB &amp; KiB (2&lt;sup&gt;10&lt;/sup&gt; bytes), MB &amp; MiB (2&lt;sup&gt;20&lt;/sup&gt; bytes), GB &amp; GiB (2&lt;sup&gt;30&lt;/sup&gt; bytes).&lt;/p&gt;
