Email Macro & Transformation

Hello,

I have a problem regarding emails interpreting special characters like '<' or '"' as &lt and &quot.

Here's what I'm doing :
I have a DataRowCollections that I'm passing to my MacroResolver.

Within my email template, I'm applying a transformation (Text/XML) on that DataRowCollection.
Transformation call in the mail template : {% itemData.ApplyTransformation("custom.transformations.TestRpt")#%}
Transformation code :
<tr style="background-color:#f1f1f1;padding:5px 10px;">
<td>{% itemNumber%}</td>
<td>{% itemName %}</td>
<td>{% itemTotalPrice %}</td>
</tr>

When I receive the email, the values contained inside itemNumber, itemName and ItemTotalPrice are correct.

BUT the html tags are not interpreted as HTML but as plain Text !

So instead of having <td>abc</td> I get "<td>abc</td>"

How can I fix this?
