[fw-general] Example of Decorator use in XML format?

[Jonathan]

Can someone give me a quick run down on how to access the decorators using 
XML?

For example, I have 3 fields that are for tire tread depth....

tread_inside
tread_middle
tread_outside

I want them to to be wrapped by an unordered list, but also with a class of 
"formInline" so I can have them display as 3 boxes inline. so...

What I want:

<ul class="formInline">
    <li>tread_inside</li>
    <li>tread_middle</li>
    <li>tread_outside</li>
</ul>


My Xml:

<elements>
    <tread_inside>
        <type>Text</type>
        <options>
            <filters></filters>
            <validators></validators>
        </options>
    </tread_inside>
    <tread_middle>
        <type>Text</type>
        <options>
            <filters></filters>
            <validators></validators>
        </options>
    </tread_middle>
    <tread_outside>
        <type>Text</type>
        <options>
            <filters></filters>
            <validators></validators>
        </options>
    </tread_outside>
</elements>

Thank you kindly for your help!
