+   Reflects a struct type, supporting polymorphic struct types.
+
+   <p>This type supersedes XCompoundTypeDescription, which only
+   supports plain struct types.</p>
+
+   <p>This type is used to reflect all of the following:</p>
+   <ul>
+       <li>Polymorphic struct type templates, like
+       <code>Struct&lt;T, U&gt;</code>.  For these,
+       com::sun::star::reflection::XStructTypeDescription::getTypeParameters()
+       returns a non-empty sequence, while
+       com::sun::star::reflection::XStructTypeDescription::getTypeArguments()
+       returns an empty sequence.</li>
+
+       <li>Instantiated polymorphic struct types, like <code>Struct&lt;long,
+       hyper&gt;</code>.  For these,
+       com::sun::star::reflection::XStructTypeDescription::getTypeParameters()
+       returns an empty sequence, while
+       com::sun::star::reflection::XStructTypeDescription::getTypeArguments()
+       returns a non-empty sequence.</li>
+
+       <li>Plain struct types.  For these, both
+       com::sun::star::reflection::XStructTypeDescription::getTypeParameters()
+       and
+       com::sun::star::reflection::XStructTypeDescription::getTypeArguments()
+       return an empty sequence.</li>
