xml Formatting Issue.

If I use the following code:

pre lang=”xml” escaped=”true”><Biml xmlns="http://schemas.varigence.com/biml.xsd"&gt;
<Packages>
<Package Name="Hello World" ConstraintMode="Linear">
</Package>
</Packages>
</Biml>

Everything is left justified and the tabs are ignored. How do I preserve the spacing? I’ve tried using the code: to no avail.
