Here is a simple example:

It's easy to make *bold text*, /italic text/, |monospace|, 
-deleted text-, super^scripts^ or _underlines_.

If we display this using <s:formattedText/>, we will get the following HTML produced:

<p>
It's easy to make <b>bold text</b>, <i>italic text</i>, <tt>monospace</tt>
<del>deleted text</del>, super<sup>scripts</sup> or <u>underlines</u>.
</p>

We can use a blank line to indicate a new paragraph, and + to indicate a heading:

+This is a big heading
You /must/ have some text following a heading!
 
++This is a smaller heading
This is the first paragraph. We can split it across multiple 
lines, but we must end it with a blank line.

This is the second paragraph.

This is the HTML that results:

<h1>This is a big heading</h1>
<p>
You <i>must</i> have some text following a heading!
</p>
 
<h2>This is a smaller heading</h2>
<p>
This is the first paragraph. We can split it across multiple 
lines, but we must end it with a blank line.
</p>

<p>
This is the second paragraph.
</p>

Ordered lists are created using the # character. Unordered lists use the = character:

An ordered list:
        
#first item
#second item
#and even the /third/ item

An unordered list:

=an item
=another item

<p>
An ordered list:
</p>
 
<ol>       
<li>first item</li>
<li>second item</li>
<li>and even the <i>third</i> item</li>
</ol>

<p>
An unordered list:
</p>

<ul>
<li>an item</li>
<li>another item</li>
</ul>

Quoted sections should be surrounded in double quotes:

The other guy said:
        
"Nyeah nyeah-nee 
/nyeah/ nyeah!"

But what do you think he means by "nyeah-nee"?

<p>
The other guy said:
</p>
        
<quote>Nyeah nyeah-nee 
<i>nyeah</i> nyeah!</quote>

<p>
But what do you think he means by <quote>nyeah-nee</quote>?
</p>

Special characters such as *, | and #, along with HTML characters such as <, > and & may be escaped using \:

You can write down equations like 2\*3\=6 and HTML tags
like \<body\> using the escape character: \\.

<p>
You can write down equations like 2*3=6 and HTML tags
like &lt;body&gt; using the escape character: \.
</p>

And we can quote code blocks using backticks:

My code doesn't work:

`for (int i=0; i<100; i--)
{
    doSomething();
}`

Any ideas?

<p>
My code doesn't work:
</p>

<pre>for (int i=0; i&lt;100; i--)
{
    doSomething();
}</pre>

<p>
Any ideas?

A link may be created using the following syntax:

Go to the Seam website at [=>http://jboss.com/products/seam].

Or, if you want to specify the text of the link:

Go to [the Seam website=>http://jboss.com/products/seam].

For advanced users, it is even possible to customize the Seam Text parser to understand wikiword links written using this syntax.

Text may even include a certain limited subset of HTML (don't worry, the subset is chosen to be safe from cross-site scripting attacks). This is useful for creating links:

You might want to link to <a href="http://jboss.com/products/seam">something
cool</a>, or even include an image: <img src="/logo.jpg"/>

And for creating tables:

<table>
    <tr><td>First name:</td><td>Gavin</td></tr>
    <tr><td>Last name:</td><td>King</td></tr>
</table>

But you can do much more if you want!
