Defining Tag Attributes for Value Expressions
Recall the use of the spinner tag:
<corejsf:spinner value="#{cardExpirationDate.year}"
id="yearSpinner" minimum="1900" maximum="2100" size="5"/>
<h:message for="yearSpinner"/>
Here is how the minimum attribute is defined in the TLD file:
<attribute>
<description>The spinner minimum value</description>
<name>minimum</name>
<deferred-value>
<type>int</type>
</deferred-value>
</attribute>
The deferred-value child element indicates that the attribute value
can be a constant string or one containing a #{...} expression
that represents an integer.
