UIParameter to implement ValueHolder
and thus support a Converter to convert the supplied value to string, if necessary.
You can use it the same way as <f:param>, you only need to change f: into
o: to get the extra support for a Converter by usual means via the converter
attribute of the tag, or the nested <f:converter> tag, or just automatically if a converter is
already registered for the target class.
Also, if no value is specified, but children are present, then the encoded output of children will be returned as
value. This is useful when you want to supply JSF components or HTML as parameter of an unescaped
<h:outputFormat>. For example,
<h:outputFormat value="#{bundle.paragraph}" escape="false">
<o:param><h:link outcome="contact" value="#{bundle.contact}" /></o:param>
</h:outputFormat>
with this bundle
paragraph = Please {0} for more information.
contact = contact us
will result in the link being actually encoded as output format parameter value.
