Objects can be put in the stack by name, like the HttpServletRequest object. Theseobjects are accessed using the "#" notation, like "#request". The "set" tag can add things to the stack by name(for example).
The only confusing bit about the way that was just described is that things put into scope are not added to the stack. There's both a stack of objects and a hash mapping names to objects. When you "set" something you're adding it to the hash table, not the value stack. To later address something in this hash table you prefix it with #.
