This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have taken this piece of TLD file from the mock exam. They have given, this is a right answer. But I have not seen <tei-class>MyTagInfo</tei-class> element so that I did not answer this option. Is there any element like this? please clear my doubt.
I don't think TagExtraInfo is on the exam, but it is an optional element on the TLD. You can use it to point to a special class you write that will check that the user of your tag uses only valid attribute values.
