About the Author

Lucinda Dykes started her career in a high-tech area of medicine, but left

medicine to pursue her interests in technology and the Web. She has been

writing code and developing Web sites since 1994, and also teaches and

develops online courses — including the JavaScript courses for the

International Webmasters Association/HTML Writers’ Guild at www.

eclasses.org .

Lucinda has authored, co-authored, edited, and been a contributing author to

numerous computer books; the most recent include Dreamweaver MX 2004

Savvy (Sybex), XML for Dummies (3rd Edition, Wiley), Dreamweaver MX

Fireworks MX Savvy (Sybex), XML Schemas (Sybex), and Mastering XHTML

(Sybex). When she can manage to move herself away from her keyboard,

other interests include holographic technologies, science fiction, and

Bollywood movies.

Ed Tittel is a 23-year veteran of the computing industry. After spending his

first seven years in harness writing code, Ed switched to the softer side of the

business as a trainer and talking head. A freelance writer since 1986, Ed has

written hundreds of magazine and Web articles — and worked on over 100

computer books, including numerous For Dummies titles on topics that

include several Windows versions, NetWare, HTML, XHTML, and XML.

Ed is also Technology Editor for Certification Magazine , writes for numerous

TechTarget Web sites, and writes a twice-monthly newsletter, “Must Know

News,” for CramSession.com. In his spare time, Ed likes to shoot pool, cook,

and spend time with his wife Dina and his son Gregory. He also likes to

explore the world away from the keyboard with his trusty Labrador retriever,

Blackie. Ed can be contacted at etittel@yahoo.com .

Dedication

To the heroes at the W3C and OASIS, sung and unsung, especially members of

the many XML working groups who have made the world (or the Web, at

least) a better place through their tireless efforts, and to all those Web pio-

neers who generously offered help and support to those of us trying to figure

out how to make our contribution to the Web in the early ‘90s.

Author’s Acknowledgments

Lucinda Dykes : Thanks to everyone on the scene and behind the scenes who

has contributed to making this project possible.

First, I’d like to thank Ed Tittel for giving me not only the opportunity to be

involved in this book, but who also played a major role in my entry into the

world of technical writing. Ed and I share a long-term interest in language,

computers, and markup languages. I’d also like to thank everyone involved in

any edition of this book for the excellent foundation they made for this edi-

tion to build on.

Next, thanks to the team at Wiley, especially Katie Feltman for her vision and

support of this project, Paul Levesque for quiet and steady guidance in addi-

tion to excellent editing, Allen Wyatt for insight and outstanding technical

editing, and Barry Childs-Helton for superb copy-editing as well as a delight-

ful sense of humor. And thanks to Carole McClendon, my agent at Waterside

Productions, who made it possible for me to lead this project.

On a personal note, special thanks to my mother, Doris Dykes, who instilled

and supported a lifelong interest in learning and in books. She claims that I’m

the first child she lost to the Internet — but that makes me easy to find. Mom:

I’ll be in front of the nearest computer screen. Thanks and love always to Wali

for making it possible for me to spend all these late nights tapping away at

the keyboard, and for always making me remember the things that are really

important. Thanks to our dear friends, Rose Rowe and Karmin Perless, who

walked softly and made room for having a writer around. And finally, thanks

to Wendy Fries and Cheryl Kline for great conversation, good advice, and lots

of laughter at our monthly writers’ session at the Coffee Grove.
