When we write '<' and '>' these characters are translated to HTML character references &lt; and &gt;

Notice, in the LAML source, how the previous paragraph is written. We make good use of the HTML transformation table.

The character < can also be written as a character entity < or <. This looks strange in the the rendered page, but take a look in the LAML source.

Special characters can also be used, for instance Λ and Ω. Please take a look in the LAML source.
