Cannot access f:selectItems variable for passthrough attribute

I am using JSF 2.2 and I want to display a title attribute on each option element generated by h:selectOneMenu with passthrough by using an attribute of the f:selectItems variable.

It seems that I cannot access the f:selectItems variable to customize my passthrough attribute

Here is what I have done so far

My entity to display

public class ItemBean {
    private int id;
    private String strName;
    private String strDescription;

    public ItemBean(int id, String strName, String strDescription) {
        this.id = id;
        this.strName = strName;
        this.strDescription = strDescription;
    }

    // Getters and Setters
}

My backbean method to retrieve the list of entities

public List<ItemBean> getItems() {
    return new ArrayList<ItemBean>(){
        {
            add(new ItemBean(1, "Java", "Java programming language"));
            add(new ItemBean(2, "PHP", "Yet another language"));
            add(new ItemBean(3, "Python", "Not a snake at all"));
        }
    };
}

My h:selectOneMenu in the view

<h:selectOneMenu>
    <f:selectItems value="#{bean.items}" var="item"
                           itemValue="#{item.id}"
                           itemLabel="#{item.strName}"
                           p:title="Description : #{item.strDescription}"/>
</h:selectOneMenu>

The problem is that I cannot access the item variable for p:title, the output is just empty there.

Here is the code generated

<select>
    <option title="Description : " value="1">Java</option>
    <option title="Description : " value="2">PHP</option>
    <option title="Description : " value="3">Python</option>
</select>

Is it possible to do it like that or is there another way ?

I finally found a solution to my problem using jstl c:forEach loop and f:selectItem from this post Using f:selectItems var in passtrough attribute

Here is the code:

<h:selectOneMenu>
    <c:forEach items="#{bean.items}" var="item">
        <f:selectItem itemValue="#{item.id}"
                      itemLabel="#{item.strName}"
                      p:title="Description : #{item.strDescription}"/>
    </c:forEach>
</h:selectOneMenu>
