ShowTip without Localization?

[ThunderSn1per]

Is this possible? When using the below code in XML it takes the value an appends '_title' to the end, how can I add this without creating a localization file? As you can see, I've tried a few things and nothing works. So the title simply reads: 'This is the actual value_title'

<action type="ShowTip" subtitle="test title" value="This is the actual value">
                <property name="Title" value="t1"/>
                <property name="title" value="t2"/>
                <property name="_title" value="t2_"/>
                <property name="Subtitle" value="t3"/>
                <property name="subtitle" value="t4"/>
</action>
