+<p>A descriptor characterises the data it represents by the length of that
+data. The length of a descriptor is the number of data items it represents:</p>
+<ul>
+<li id="GUID-3AF8F237-CA2A-5AAF-A56E-ECC7C95907B7"><p>for 8 bit variant
+descriptors, the length is the number of single-bytes of data. When the descriptor
+represents non-Unicode strings, the length is the number of characters in
+the string.</p> </li>
+<li id="GUID-7610BC67-31CD-57DA-A72C-B1F4348C8FAC"><p>for 16 bit variant
+descriptors, the length is the number of double-bytes of data. When the descriptor
+represents Unicode strings, the length is the number of characters in the
+string.</p> </li>
+</ul>
+<p>The length of a descriptor cannot be greater than 2<sup>28</sup>.</p>
+<p>The size of a descriptor is the number of bytes occupied by the data represented
+by that descriptor:</p>
+<ul>
+<li id="GUID-830C6F31-EE2D-5C30-91D4-AB15FE4D2BA5"><p>for the 8 bit variant
+descriptors, the size is the same as the length.</p> </li>
+<li id="GUID-C7AF88D8-5836-53B9-A991-EA97B539C7CF"><p>for the 16 bit
+variant descriptors, the size is twice the length.</p> </li>
+</ul>
+<p>The descriptors which allow their data to be modified are also characterised
+by a maximum length. This represents an upper limit on the length of data
+the descriptor can represent, i.e.the length of data represented by the descriptor
+can vary can vary from zero up to, and including, this maximum value.</p>
