well,
generell JSF EL is able to do:
-arithmetics (+, -, *, / or %)
<h:outputText value="#{100 * 1.16}"/>)
-relational (<, >, <=, >=, == or != -->)
<h:outputText value="#{backingBean.int!=42}"/>)
-logical (&&, || or !)
<h:outputText value="#{backingBean.bool1&&backingBean.bool2}"/>
-empty operator
<h:outputText value="#{empty bean.vector}"/>
and contrains:
<h:outputText value="#{backingBean.property ? 'TRUE' : 'FALSE'}"/>
HTH,
Matthias
