Praise for Essential XML
Quick Reference
“I think it is a wonderfully clear and concise summary of a great deal of key XML
material. I expect it to find a well-thumbed home on my bookshelf.”
—Mary Holstege, PhD,
XML Architect, mathling.com, and W3C XML Schema Working Group Member
“This book is a unique collection of reference material on the most relevant XML-
related standards, which takes the important W3C recommendations and puts
them all in context. Something that definitely needs to be on every XML devel-
oper's desk!”
—Alexander Falk,
President and CEO of Altova, Inc. - The XML Spy Company
“Essential XML Quick Reference proves that Aaron Skonnard and Martin Gudgin
can distill the essence of a very large, complicated topic like XML into easy to
understand, bite-sized pieces. It’s an invaluable asset!”
—Brad Wilson,
Principal Software Architect, Quality Software Development
“Essential XML Quick Reference is one of the few printed references I would actu-
ally buy.”
—Don Box,
Series Editor, The DevelopMentor Series
“The full specification is quite verbose. Having the pocket reference makes life
simpler when it comes to the ‘What was the name of that element again?’ or ‘What
were the order of the parameters to that function?’ type questions. When I need a
quick, concise, answer, I don’t want to have to thumb through hundreds of pages
before getting the answer I need. This book is a very welcome, often relied upon,
addition to my developer tool belt.”
—Drew Marsh,
Senior Architect, Mimeo.com, Inc.

“I’ve read most of the documents regarding XML on the W3C site; the language
definitions and standardization jargon makes them unapproachable to most devel-
opers. This book makes the concepts make sense by giving concrete examples
showing the different syntax variations. Essential XML Quick Reference is a com-
prehensive reference book that will bridge a gap that hasn’t been filled. Almost
anyone from basic to advanced skills will be able to use this book and I know I will
keep it within arm’s reach at work. It’s a source that I will be able to go to in order
to lookup subtle syntactic information that eludes me.”
—Justin Burtch,
Software Engineer, Integrated Data Systems
