Suppose, that as part of documenting your code (Javadoc) you want to indicate that the relationships between elements using deep indentation.
How can I create a nested list as:
<ul>
<li>Element</li>
<ul>
<li>Subelement...</li>
You can pretty freely use HTML inside javadoc comments.
Update: Because it came up, I tried
<ul>
<li>one</li>
<ul>
<li>one point one</li>
</ul>
</ul>
and get
I agree proper nesting is better.
