Fieldset/legend at pages problem

Has anyone tried this at pages, I wonder I cannot make it work at it should be quite simple?
The folllowing just shows me "Germany" and "1.2.3" at my page, and no fieldset and legend.

Code:

<FIELDSET>
<legend>Germany</legend>
1.
2.
3.
</FIELDSET>

Thanks, unfortunately I could not find the solution at this page. If others have a specific solution, I am still interested
