Take a look in possible atributes to use in items.xml. I guess those are compatible with our version.
[TFS 0.3+] ALL possible item attributes (FULL LIST + "How to" for other TFSs). Hey there everyone! I was just checking some files on my old OT and I remembered that when I was new (and even not so new), I always had a HORRIBLE time trying to figure out which were the possible Item Attributes...

I have an armor who increase magic percent +15% and ML +4, thats how item attribute must be:
XML:
<attribute key="weight" value="3000"/>
<attribute key="armor" value="15"/>
<attribute key="slotType" value="body"/>
<attribute key="increaseMagicPercent" value="115"/>
<attribute key="description" value="Magic Damage +15%."/>
<attribute key="magiclevelpoints" value="4"/>
</item>
