Just use the and and ref condition ;-)

<condition type="and" id="clientandstruts">
   <condition type="ref" refid="client_select_var"/>
   <condition type="ref" refid="struts_selected" />
</condition>


Btw, there are also Not, Or, Xor conditions. 
For most cases, the already implemented conditions should be enough, but
if there is a condition type, which is not available at the moment, you
can implement one by deriving the abstract base class
com.izforge.izpack.rules.Condition
Your new condition should be in the same package. At the moment it has
to be named <Yourname>Condition.java and the only the first character of
<Yourname> has to be capital. The new condition could then be referenced
like:

<condition type="<Yourname>" id="">
...
</condition>
