+Ports of this type may be connected to buffers of several types.  The plugin
+provides a set_type function for the host to specify which type a port is
+currently connected to.
+
+A Port specifies the types it supports using the :supportsType property.
+The type specific in the normal LV2 manner (&lt;port&gt; a &lt;sometype&gt;)
+is the "default type".  If the port is connected without set_type being called
+for that port, the type of the buffer is assumed to be the default type.
+In this way polymorphic plugins are backwards compatible and may be used by
+hosts which are not aware of the polymorphic port extension.
