public class Converter extends ConverterHandler
<o:converter> basically extends the <f:converter> tag family with the
possibility to evaluate the value expression in all attributes on a per request basis instead of on a per view
build time basis. This allows the developer to change the attributes on a per request basis.
When you specify for example the standard <f:convertDateTime> by
converterId="javax.faces.DateTime", then you'll be able to use all its attributes such as
pattern and locale as per its documentation, but then with the possibility to supply
request based value expressions.
<o:converter converterId="javax.faces.DateTime" pattern="#{item.pattern}" locale="#{item.locale}" />

Converter based on the binding and/or converterId

attributes. Then create an anonymous Converter implementation which wraps the created
Converter and delegates the methods to it after setting the render time attributes. Finally set the
