<DL>
<DD>information on scripting variables defined by the tag associated with
 this TagExtraInfo instance.
 Request-time attributes are indicated as such in the TagData parameter.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>data</CODE> - The TagData instance.

<DD>Translation-time validation of the attributes. 
 Request-time attributes are indicated as such in the TagData parameter.
 Note that the preferred way to do validation is with the validate()
 method, since it can return more detailed information.

<DL>
<DD>Translation-time validation of the attributes.
 Request-time attributes are indicated as such in the TagData parameter.
 Because of the higher quality validation messages possible, 
 this is the preferred way to do validation (although isValid() 
 still works).  
 
 <p>JSP 2.0 and higher containers call validate() instead of isValid().
 The default implementation of this method is to call isValid().  If 
 isValid() returns false, a generic ValidationMessage[] is returned
 indicating isValid() returned false.</p>
