ADF Faces IF statement available within the page?

Question

I am making a page using ADF Faces.
I want to create an IF statement in a page that will display some markup on one condition and on another display some other markup.
For example, I am using an iterator to build a table. I would like to have the background color of the row alternate based on the iterator count % 2 ( also how can I get the count of the iterator).
Also, I would want to make the text color highlight based on some condition such as is foo==bar make the text red etc.
Anyone know how to do this simple simple task in ADF Faces?
**Note the if from JSF core is not available in Jdeveloper for whatever reason. Any help would be appreciated.
Also, I don't want to just set some property of some element based on a condition with EL.
Lets say there is a whole section of the page that I only want to show is a condition is true. Is this impossible in ADF Faces? Is there something fundamental I am missing about this framework?

For conditional rendering of group of fragments, you can use switcher component.
See the sample for switcher here: http://jdevadf.oracle.com/adf-richclient-demo/faces/components/switcher.jspx
Code:
<af:switcher id="s1" defaultFacet="#{<CONDITION> == 'true' ? 'two' : 'three'}">
<f:facet name="two">
<af:outputText id="ot2" value="Two"/>
</f:facet>
<f:facet name="three">
<af:outputText id="ot3" value="Three"/>
</f:facet>
</af:switcher>
For changing the text color based on the condition, you could use the EL expression in InlineStyle (it is a simple case) Otherwise, you can use skinning to change the same.
Sample:
<af:outputText id="ot4" value="#{bindings.FirstName.inputValue}"
inlineStyle="#{bindings.FirstName.inputValue == 'Steven' ? 'color:red' : null}"/>
