Tag name: <f:param>
UIComponent class: javax.faces.component.UIParameter
Tag class: org.apache.myfaces.taglib.core.ParamTag
Component type: javax.faces.Parameter

This tag associates a parameter name-value pair with the nearest parent UIComponent. A UIComponent is created to represent this name-value pair, and stored as a child of the parent component; what effect this has depends upon the renderer of that parent component.

Unless otherwise specified, all attributes accept static values or EL expressions.
