This paper will cover the following topics: HTML vs. XHTML; XHTML modularization and XHTML Basic; well-formed XML documents; names and namespaces; global attributes and XLink; namespace URI and RDDL (XHTML Basic + XLink).

XSL Formatting Objects (XSL-FO) are the second half of the Extensible Stylesheet Language (XSL). XSL-FO is an XML application that describes how pages will look when presented to a reader. A style sheet uses the XSL transformation language to transform an XML document in a semantic vocabulary into a new XML document that uses the XSL-FO presentational vocabulary. While one can hope that Web browsers will one day know how to directly display data marked up with XSL formatting objects, for now an additional step is necessary in which the output document is further transformed into some other format, such as Adobe's PDF.

XPointer, the XML Pointer Language, defines an addressing scheme for individual parts of an XML document. These addresses can be used by any application that needs to identify parts of or locations in an XML document. For instance, an XML editor could use an XPointer to identify the current position of the insertion point or the range of the selection. An XInclude processor can use an XPointer to determine what part of a document to include. And the URI in an XLink can include an XPointer fragment identifier that locates one particular element in the targeted document. XPointers use the same XPath syntax that you're familiar with from XSL transformations to identify the parts of the document they point to, along with a few additional pieces.

XML Schema is one of the most important facets of Web Services. It is the ultimate type system; however it is also really arcane to learn a figure out how to leverage. Drill into what's important for you understand in order to get the most out of specification. Learn about schema creation best practices, where to start and what tools to use, versioning, serialization and validation of messages. Walk away with a clear understanding on how and why to use XML Schema, .NET Framework support and how schema drives WSDL and Web Service message parsing.

The recent rush to adopt XML can be attributed in part to the hope that the static typing provided by DTDs (or more sophisticated mechanisms such as XML-Schema) will improve the robustness of data exchange and processing. However, although XML documents can be checked for conformance with DTDs, current XML processing languages offer no way of verifying that programs operating on XML structures will always produce conforming outputs.

Provides a central location for everything that a developer needs to know about XML technologies (XML, XSLT, XLL, SVG and about 40 other categories). You will find examples with Source Code, Tutorials, Tools, Resources, Books, etc.

When designing XML and Web services schemata you will often (and ideally) reuse data elements defined in pre-existing standards. If so, it is extremely useful to include links to such standards, providing precise data dictionary references. In so doing, you make processing and maintenance easier to automate. This tip illustrates this practice.

This introduction to XML presents the Extensible Markup Language at a reasonably technical level for anyone interested in learning more about structured documents. In addition to covering the XML 1.0 Specification, this article outlines related XML specifications, which are evolving. The article is organized in four main sections plus an appendix.

In this article, the author examines how JAX-RPC SOAP handlers process SOAP message headers. Specifically, he shows how a handler adds a SOAP header to an outgoing message and how a corresponding handler removes the SOAP header from an incoming message. In addition, he presents the JAX-RPC programmatic configuration and deployment models as they relate to this topic.
