   Reflects a struct type, supporting polymorphic struct types.

   <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,
       <member scope="com::sun::star::reflection"><!--
       -->XStructTypeDescription::getTypeParameters</member> returns a non-empty
       sequence, while <member scope="com::sun::star::reflection"><!--
       -->XStructTypeDescription::getTypeArguments</member> returns an empty
       sequence.</li>

       <li>Instantiated polymorphic struct types, like <code>Struct&lt;long,
       hyper&gt;</code>.  For these,
       <member scope="com::sun::star::reflection"><!--
       -->XStructTypeDescription::getTypeParameters</member> returns an empty
       sequence, while <member scope="com::sun::star::reflection"><!--
       -->XStructTypeDescription::getTypeArguments</member> returns a non-empty
       sequence.</li>

       <li>Plain struct types.  For these, both
       <member scope="com::sun::star::reflection"><!--
       -->XStructTypeDescription::getTypeParameters</member> and
       <member scope="com::sun::star::reflection"><!--
       -->XStructTypeDescription::getTypeArguments</member> return an empty
