My experience with 141 certification

hi guys,
I have written xml certification yesterday and cleared it with 70% score( it is not the best score I know). However I would like to share my experience. I looked at javaranch and other forums, Most of the times it was projected that XML certification is the tougest exam. I don't think so. It is diffinitely tough but nothing to frighten about. I have read the postings of jayadev and some others guys in this post. I am really impressed with their understanding of concepts and I feel that they can easyly make it.(Jayadev why wait mate, go for the exam unless you are pressed for time in your project) I have seen the big recomonded lists. which includes xml-rpc, security etc. I haven't covered topics like signatures, encryption and XML-Databases stuff. still I have cleared the exam.
O.K I will give some of my questions.
number of questions are 55.
Pass mark is 58% So be prepared for it.
Tons of scenario based questions (no mock test covers this many)
Lot of emphasis on schema, DTDs, XSLT, like what is the correct implementation / various types of content models.
DTD and Schemas all particles of schema like list, union, enumaration, all, any , simple type, complex type are covered in one way or other)
Comparisions, Limitations in a given scenario.
Not many direct questions.
Time is just sufficent but not plunty(at least for me as I have got many scenario questions.reading them alone took lot of time). So you have to plan your time properly. I coudn't find time to review all my questions. so give your best shot when you read it or leave it completely for next round.but dont do half-half. You will be loosing time twice. As it is said in the earlier post they are very reading-intensive.
I have completed my first round of answers in 1 hour 15 minutes. and revisited remaining 8 to 10 questions I left in 2nd round.
some questions I can remember is
(forgive me for my spellings)
one question on validation of a document againest DTD (easy).
one question on validation of a document againest Schema.(easy)
Customer & Item scenario to identify the relationship uniquely(use of id and idref).
one question on xsl:fo. but like to which parent a perticular child element belongs to whether fo:block or fo:flow .. etc.
none on signature/encription
couple questions on SOAP, WSDL. however they are not in depth techie questions. It was like in a buiseness scenario.There are two bussiness entities, one is manufacturing company other is a supplier. how to find for the (web)service? whether to use the UDDI look up or not.
In general I believe we should have overall understanding of web services and how it works. but need not know about finer details of Implementations or programming.
how a document is completely represented using the following (select 5 choices)
self::
ancestor::
descident::
following::
presceding::
following-sibling::
presceding-sibling::
atleast 3 questions from mockexams (all scenario based)
Atleast 5 questions on DOM & SAX.
so In general I think one shoud concentrate on core technologies like DTDs & Schemas, XSLT, DOM & SAX , XPath &XPointer.

as always said IBM mock test is the best one. no other is near to real exam.
no other is any whare near that.

best of luck

Congratulations Satya. I appreciate your take on the "toughness" of the exam - I admit to some trepidation after reading so many 'toughest exam' posts. Also, thanks for remembering and recording the specifics of your exam. Good luck going forward.

Congrats Satya; It is a wonderful score, plus your post has been extremely useful.
However You mentioned one of the question
how a document is completely represented using the following (select 5 choices)
self::
ancestor::
descident::
following::
presceding::
following-sibling::
presceding-sibling::
I could not understand what does this question mean.

Zeeshan,
Just to answer the previous Q. about unabbreviated syntax axes:
The 5 correct choices are: ancestor, descendant, following, preceding and self:
See an excerpt from the XPath Recomendation
(http://www.w3.org/TR/xpath#axes ):
"NOTE: The ancestor, descendant, following, preceding and self axes partition a document (ignoring attribute and namespace nodes): they do not overlap and together they contain all the nodes in the document."
All other additional axes can be built combining these 5 ones using logical operators and functions. They are added for convinience, I guess.
Take care,
Svetlana.

Thank you Svetlana for answering on my behalf.
I haven't expressed the axes question properly. It was my mistake.
I am glad that my post is useful for some of us.
