An XML Pipeline specifies a sequence of operations to be performed on a collection of XML input documents. Pipelines take zero or more XML documents as their input and produce zero or more XML documents as their output.A pipeline consists of steps. Like pipelines, steps take zero or more XML documents as their input and produce zero or more XML documents as their output. The inputs to a step come from the web, from the pipeline document, from the inputs to the pipeline itself, or from the outputs of other steps in the pipeline. The outputs from a step
XML is a versatile markup language, capable of labeling the information content of diverse data sources including structured and semi-structured documents, relational databases, and object repositories. A query language that uses the structure of XML intelligently can express queries across all these kinds of data, whether physically stored in XML or viewed as XML via middleware. This specification describes a query language called XQuery, which is designed to be broadly applicable across many types of XML data sources.

W3C Working Draft 16 July 2007:
Abstract
This document is the specification of the Efficient XML Interchange (EXI) format. EXI is a very compact representation for the eXtensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources. The EXI format uses a hybrid approach drawn from the information and formal language theories, plus practical techniques verified by measurements, for entropy encoding XML information. Using a relatively simple algorithm, which is

Abstract
This Working Group Note presents measurement results of various high-performance XML interchange encoding formats and their associated processors, made by the Efficient XML Interchange (EXI) Working Group. The measurements have been conducted following the recommendations of the XML Binary Characterization (XBC) Working Group. In particular, this draft covers measurements of the properties of "compactness", "processing efficiency" and "roundtrip support", as defined by the XBC WG. We start by describing the
We’ve come a long way since the beginning of our journey toward XML mastery. In the last article of his series, Frank Coyle examines XML-related security issues. We begin by looking at the family of XML security standards and then move on to the threat of black-hat attacks and what you can do to safeguard your XML-based applications.
The XML Encryption Standard
XML encryption is an XML vocabulary for working with public key encryption. You may wonder why a separate vocabulary is needed for sending XML over the Internet, when Secure Sockets Layer
XML Encryption provides end-to-end security for applications that require secure exchange of structured data. XML itself is the most popular technology for structuring data, and therefore XML-based encryption is the natural way to handle complex requirements for security in data interchange applications. Here in part 1 of this two-part series, Bilal explains how XML and security are proposed to be integrated into the W3C's Working Draft for XML Encryption.
Currently, Transport Layer Security (TLS) is the de facto standard for secure communication over

Abstract:
XML Schema Part 0: Primer is a non-normative document intended to provide an easily readable description of the XML Schema facilities, and is oriented towards quickly understanding how to create schemas using the XML Schema language.
XML Schema Part 1: Structures and XML Schema
Part 2: Datatypes provide the complete normative description of the XML Schema language. This primer describes the language features through numerous examples which are complemented by extensive references to the normative texts.
