I passed the test today and I thought I'd pass along my experience which more or less confirms what others have offered. The test itself is indeed heavy on DTD, XSL and XML Design. There was a business case where they ask you architecture and design questions. They also ask you questions on how to achieve a desired result from the application provided. (Ajith's sample test on Design is a good test of your understanding of these concepts). I only had one question where XML & XSL were supplied and the output was asked for. (easy) One question on xsl-fo, XLink, and schema. IMO: Don't bother with the specifics of these, just know the general specs. Know XPath! 4-5 questions. For this, use the tutorial at www.zvon.org and the w3 specs (the XPath specs are straightforward and not so long). For good examples of XPath -- use Wrox's XSLT - Programmer's Reference by Michael Kay, Chapter 5. I also strongly recommend going through Michael Kay's book for XSLT. It is an excellent source. There are many good examples on www.zvon.org, but I didn't find them as useful as the book for the high-level type of questions that were asked. There were approx 5 questions where the DTD or some specs were given and you had to choose which answer conformed. (For DTD I used Wrox's Professional XML). 5-6 question on DOM & Sax: Again Wrox's Professional XML helped. Overall: I would say that syntax was only an issue in 4-5 questions. Most questions were high-level, designed to test your understanding of the concepts. Alot of common sense and a decent grasp of specs should get you by. As mentioned before. Time is an issue. Manage it wisely. Hope this helps.
