+class is useful for constructing an array of variable length buffers, where
+the length is decided at run time. It is also useful as a data member of a
+base class in a thin template class/base class pair, where the type of the
+array element is not known until the owning thin template class is instantiated.</p> <p>For
+example, to implement a stack of packed (variable length) objects of type <codeph>T</codeph>.</p> <codeblock id="GUID-C6370DDF-44D6-52BA-A0C3-898F66918210" xml:space="preserve">class CExampleBase : public CBase
