#39 < can not be properl written in Activity Diagram

[Anonymous]

in the following:
<void method="connect">
<object class="com.horstmann.violet.product.diagram.activity.ActivityTransitionEdge">
<void property="bentStyle">
<object class="com.horstmann.violet.BentStyle" field="STRAIGHT"/>
</void>
<void property="endArrowHead">
<object class="com.horstmann.violet.ArrowHead" field="V"/>
</void>
<void property="middleLabel">
<string>i &lt; = 10</string>
</void>
</object>
<object idref="DecisionNode0"/>
<object idref="ActivityNode3"/>
</void>

the term &lt; is not interpreted right. So the < sign is not shown in the diagram
