Overview of the Feature Pack for XML

IBM® WebSphere® Application Server Version 7.0 feature packs are optionally installable product extensions that offer targeted, incremental new features. The IBM WebSphere Application Server Version 7.0 Feature Pack for XML delivers critical technology that enables adoption of key XML standards and principles.

XML-structured data has become the predominant format for data interchange. XML data is navigated, queried, or transformed in almost every existing WebSphere application.

Since first being standardized, XML usage in application-development environments has grown significantly to include many scenarios. WebSphere Application Server is a leading platform for the latest application development standards, including XML.

The Feature Pack for XML provides application developers with support for the following World Wide Web Consortium (W3C) XML standards:
Extensible Stylesheet Language Transformations (XSLT) 2.0
Programming language used to transform XML into a new XML format or into another presentation-oriented format such as HTML, XHTML, or SVG

For more information about this standard, go to XSL Transformations (XSLT) Version 2.0.

XML Path Language (XPath) 2.0
Programming language designed to allow developers to select nodes from an XML document

For more information about this standard, go to XML Path Language (XPath) 2.0.

XML Query Language (XQuery) 1.0
Query language built with the intent of enabling access to collections of XML documents in a way that bridges retrieval of both structured and unstructured data

For more information about this standard, go to XQuery 1.0: An XML Query Language.

These new and updated W3C XML standards offer application developers numerous advanced capabilities for building XML applications. Specific benefits delivered in the XPath 2.0, XSLT 2.0, and XQuery 1.0 standards include the following:
Note: If you want to use XPath 1.0 or XSLT 1.0 (not in backwards-compatibility mode), continue to use Java™ API for XML Processing (JAXP) in Java 2 Platform, Standard Edition (J2SE) 1.6.

For more information about these W3C XML standards, go to W3C XQuery 1.0 and XSLT 2.0 Become Standards: Tools to Query, Transform, and Access XML and Relational Data.

The Feature Pack for XML also provides the IBM XML Application Programming Interface in support of these standards. This application programming interface invokes a runtime engine that is capable of executing XPath 2.0, XSLT 2.0, and XQuery 1.0 as well as manipulating the returned XML data.

The Feature Pack for XML includes the IBM Thin Client for XML with WebSphere Application Server. The thin client allows access to the same feature-pack API and runtime functionality (XPath 2.0, XSLT 2.0, and XQuery 1.0) available in the Feature Pack for XML. The thin client can be copied to multiple clients running Java SE in support of a WebSphere Application Server Version 7.0 installation.
