is that there are too many esoteric, unpractical topics like XSL:FO, XLink I mean who uses this stuff really? Maybe a few, but why have a standardized test to show competency when so few projects out there use them?
I think they should have stuck with the practical stuff which is actually used like XSLT, Schemas, DTDs, DOM, SAX. That's about it! Why even certify people in the other technologies which are hardly ever used?
I am slowly preparing for this test, one aganozing part is XLink, which I find covered very poorly in XMP Prof 2ed !! I'm unclear about inline, extended, etc...
Does anyone have a good link to an online tutorial/explanation of XLink??
I tried to find one on JavaRanch but it gets difficult to sort through all the messages to find a link to a resources page which might contain this info, though I know it must exist on this site somewhere considering all the hard work that goes on by the dedicated ranchers.
Thanks and l8r

Is there a way to tell Xalan processor to validate your input document against a DTD or Schema before transformation? I know it's possible on the command line, but I can't figure out how to get the Transformer's underlying parser implementation to set it's validating property to true!
Thanks
Could someone who has taken the test answer whether or roughly how many questions present an XML document and accompanying XSLT stylesheet and ask what the result will be?
Thanks
OK, I think I'll go apply for a dishwashing job now.

Professional XML 2nd Edition
I just finished reading the Wrox Professional XML 2ed cover to cover. I took the sample test today and just barely missed passing ( I thought the test was tough!) . Because I had very little exposure to XML before, maybe this is useful for someone in my situation. I think with a better memory, I would have passed today essentially from what the book taught me ( I used some outside resources, but few).
The upshot on this book with respect to the cert is that it covers most of what you need, and is the only book I found which does so for 141. This includes fairly detailed chapterS on Web Services. However, at 1100+ pgs it doesn't cover things concisely. Might make a good refernce in the future if I ever use this technology. For someone who likes to have a book on the shelf as opposed to bookmarks in their browser, I give this book a "B" grade.
If you're a web jockey who can learn from material online, there are equally good tutorials and other resources posted on JavaRanch (from what I've seen / skimmed ) . But I like to highlight my book up, and carry it with me (keeps me in shape ).
Of course either way, setting up parsers & messing around with actual examples etc is a must.
I hope this helps people who are browsing titles for the exam.
Who is taking the exam soon? I'd like to hear how it compares to the sample on IBM's website. I hope it's easier, or else I've got some reviewing and additional resource hunting to do.
I'm looking at implicit restrictions on a string namely, specifying a length in the instance
document will disallow specifying maxLength or minLength.
I thought I'd work backwards and reason how this could have been done in the Schema for Schemas
It is logical that if you specify an exact length, that neither maxLength nor minLength can be relavent. Yet I don't see where this restriction is in the Schema for Schemas
If I were creating a derivedType to do this, I can only think to use groups and complex choice to achieve this kind of logic seemingly built-in for the string type.
Is there an assumed logic in parsers that having one specified disallows the other, or something here ( Schema for Schemas)
http://www.w3.org/TR/xmlschema-1/#normative-schemaSchema
I'm not seeing?
This is what I'm reading, but is SAX an API or just a set of interfaces which a specific implementaion must, well, implement?
I am reading Wrox Prof XML 2e, which asserts that "SAX is an API"
OK, I think I'm getting the feel for schema now, but it was a bit of a struggle at first!
I have a question, could have started a new thread I guess but here it goes:

OK -- I got it, the W3C primer is pretty good so is your link Satish.
XML is a funny topic to study, you can't really "mess around" like you can with learning a programming language.
Thanks
I'm studying for the IBM XML cert, and am at Schema chapter in my Professional XML 2e Wrox book. I understood DTDs w/o problem now come to what is supposed to be easier Schema and find the whole utterly confusing. I am no brainiac, but have cleared SCJP and SCWCD with little conceptual difficulties. I thought part of the impetus for XML Schema is to be more transparent.
I've been to a couple of the suggested links from previous posts, does anyone else have a favorite link they think provides a readable concise overview to get an aspiring XMLer into this without falling asleep and drooling???
I'm gonna try the W3C non-normative primer now, but given the esoteric nature of the other W3C docs, I ain't holding my breath!!
Maybe this ought to go in the new XML cert discussion, dunno
Thanks and

Thanks for useful discussion, I can see I started something that went a little beyond but that's OK by me.
BTW, still no job and I'm going for the XML cert from IBM... we'll see if that helps. I think I need to be making more telephone ( I'm not super gregarious ) calls.

Thanks to everyone for their responses, I am slowly working my way through this massive book. It's OK but suffers from the too many author syndrome. I can't believe how much information there is to take in about this topic, then J2EE on top of this?? Wow, with every new Java related endeavor I have more respect for the professional Java programmers out there.
Well I bought the Professional XML book, but it isn't written all that well IMO. Maybe it gets better as the plot thickens.
Will keep the board apprised, especially WRT the exam
