See my last message about multipart stuff. You can capture this
functionality in TEI (TagExtraInfo) Support class to your tag. Then in
your tag you can set the value of the variable via a special method
which you have to define.
<!-- Straight off the javadoc
public abstract class TagExtraInfo
extends java.lang.Object
Optional class provided by the tag library author to describe additional
translation-time information not described in the TLD. The TagExtraInfo
class is mentioned in the Tag Library Descriptor file (TLD).
This class can be used:
* to indicate that the tag defines scripting variables
* to perform translation-time validation of the tag attributes.
