<equals>
#
The <equals>
element is used inside a <conditional>
to check if a property is equal to a
certain value.
The type of a value may be implicit:
<condition>
<equals>
<property>/engines/engine[0]/running</property>
<value>true</value>
</equals>
</condition>
Or explicit:
<condition>
<equals>
<property>/engines/engine[0]/running</property>
<value type="bool">true</value>
</equals>
</condition>
