        tagdependent    The body of the tag is interpreted by the tag
        		implementation itself, and is most likely

  <xsd:complexType name="tld-deferred-methodType">

        Defines information about how to provide the value for a
        tag handler attribute that accepts a jakarta.el.MethodExpression.
        
        The deferred-method element has one optional subelement:
        
        method-signature  Provides the signature, as in the Java
        Language Specifies, that is expected for 
        the method being identified by the 
        expression.

          <xsd:documentation>

            Provides the expected signature of the method identified 
            by the jakarta.el.MethodExpression.
            
            This disambiguates overloaded methods and ensures that 
            the return value is of the expected type.
            
            The syntax of the method-signature element is identical 
            to that of the function-signature element.  See the 
            documentation for function-signature for more details.
            
            The name of the method is for documentation purposes only 
            and is ignored by the JSP container.
            
            Example:
            
            boolean validate(java.lang.String)

        The tld-extensionType is used to indicate
        extensions to a specific TLD element.
        
        It is used by elements to designate an extension block
        that is targeted to a specific extension designated by
        a set of extension elements that are declared by a
        namespace. The namespace identifies the extension to
        the tool that processes the extension.
        
        The type of the extension-element is abstract. Therefore,
        a concrete type must be specified by the TLD using
        xsi:type attribute for each extension-element.

        The extensibleType is an abstract base type that is used to
        define the type of extension-elements. Instance documents

        extension-elements.
