<Comment>
The <code>sidl</code> package contains the fundamental type and interface
definitions for the <code>SIDL</code> interface definition language. It
defines common run-time libraries and common base classes and interfaces.
Every interface implicitly inherits from <code>sidl.BaseInterface</code>
and every class implicitly inherits from <code>sidl.BaseClass</code>.
