Correct. I was talking about JSP 1.0 and JSP 1.1 implementations; anything
prior to JSP 1.0 was an implementation of an unfinished specification. If
you use this kind of product you need to be aware that anything can change
when the spec is finalized, and yes, that things may differ dramatically
between implementations. If a JSP 1.0/1.1 implementation doesn't provide all
the defined implicit variables, though, it's clearly a bug.
