There are two major <span class="emphasis"><em><span class="bold"><strong>aspects</strong></span></em></span>
or <span class="emphasis"><em><span class="bold"><strong>views</strong></span></em></span> of icl containers.
The first and predominant aspect is called <span class="emphasis"><em><span class="bold"><strong>fundamental</strong></span></em></span>.
The second and minor aspect is called <span class="emphasis"><em><span class="bold"><strong>segmental</strong></span></em></span>.
