satya - Well, I'm one of those people who like to read code.
In TC 4.01 it's a HashTable, declared private, in TagSupport. The getValue, getValues, removeValue, setValue public methods
are not used by local code. BodyTagSupport does not call any of these methods either.
So .... it seems like a built-in lookup mechanism for any user tag handler code to use. I sure don't see any
doc's on this anywhere 'tho. Also, why no mechanism to 'getKeys'?
