XML Family of Specifications: A Practical Guide
March 29, 2002
In this chapter, we cover the rules of XML syntax that are
stated or implied in the XML 1.0 Recommendation from the W3C. A
considerable amount of XML terminology is introduced, including
discussions of pars-ing, well-formedness, and validation. XML
document structure, legal XML Names, and CDATA are also among
the topics.The XML 1.0 specification also discusses rules for
Document Type Definitions (DTDs), which we present in chapter 4.
The material in chapters 3 and 4 is very interrelated.
Who is this book for?
As XML continues to mature, developers need to understand how
this standard and its related technologies are revolutionizing
software development. XML Family of Specifications provides a
complete roadmap for understanding how XML, XSL, XML Schema, and
related specifications interlink to create powerful, real-world
applications.
