You'll find the word enum in the '==' section.

We added just a few things to the new version:
- we fixed some technical errors
- add wrote a new batch of questions
- we added a very view new topics - most notably we added a section on dynamic attributes. You can find that same discussion here at the ranch - also written by Bryan.
So, long story short, if you're really rich go ahead and buy the new version - if you're not rich, the old version plus Bryan's write-up will be fine.

My main criticism would be the questions at the end of the chapter.
For example, I have recently finished Chapter 10 - Custom Tag Development, and eagerly moved on to the questions to see how much I had retained...
Q2 talks of jsp:invoke, but I cannot find this in the chapter?
Q3 doesn't have a valid answer (in errata)
Q7 talks of Dynamic Attributes - but these weren't in the chapter?
Q8 answer contains an error (in errata)
Q9 answer contains an error (in errata)
Q13 contains an error (in errata)
Q17 contains a clarification (in errata)
Chapter10 is HUGE so I could easily have missed the bits needed for Q2 and Q7, and would appreciate anyone who can point them out in chapter10 for me?
And chapter10 isn't unique - most contain new things not in the chapters.
Just wanted to make the point that when studying, coming across things you have never heard of and scoring low in end of chapter tests can have really adverse effects on your confidence.
Is the idea that I should have read the spec so would know what these things not covered are? In which case, doesn't this defeat the idea of the study guide?
Just to reiterate - I have honestly found the book to be excellent and ideal for introduction to concepts - I just have this minor niggle ;-)
Hope that helps,
