The W3C recommendation allows any digital data to be signed, and this includes an XML document, an XML element of a document, and the content of an XML element as particular cases.
When we talk about an XML signature, we are actually referring to an XML document, which contains the Signature (defined in the namespace http://www.w3.org/2000/09/XMLdsig#) as one element (which may be the root element). But the document may also contain other elements, among which the most important are, of course, the original data objects being signed.

There was a question on Mark Birbeck's mind. Should Xpath feature CSS? "But while some sort of convergence of XPath and CSS selectors may seem an obvious thought to many, the CSS 'language' continues to resist being brought up to date, and instead exists in a strange, murky world, of 'quirkarounds' and 'standards-proprietary' syntax. (As people require the ability to address other parts of the source tree, new selection mechanisms have to be added, but in a way that doesn't affect existing rules -- resulting in 'quirky workarounds', and syntax that is
"When Internet Explorer 5.0 was first shipped in 1998, Microsoft shipped an implementation of XSL that was based on the current working draft of XSL at that time. Millions of copies of this XML/XSL processor were burned on CDs and were installed on systems all around the world. Since then, the XSLT specification changed very significantly (even the namespace changed!) and was finalized. So the situation as it is today (12/4/2000) is that there are millions of copies of a parser out there which does not (by default) support the latest XSLT
XLink Attribute Usage Patterns
While the XLink attributes are considered global by virtue of their use of the namespace mechanism, their allowed combinations on any one XLink element type depend greatly on the value of the special type attribute (see [XLink Element Type Attribute (] for more information) for the element on which they appear. The conformance constraint notes in this specification detail their allowed usage patterns. Following is a summary of the element types (columns) on which the global attributes (rows) are allowed, with an
XLink Markup Design
This section describes the design of XLink's markup vocabulary.
Link markup needs to be recognized reliably by XLink applications in order to be traversed and handled properly. XLink uses the mechanism described in the Namespaces in XML Recommendation [xname] to accomplish recognition of the constructs in the XLink vocabulary.
The XLink namespace defined by this specification has the following URI:
http://www.w3.org/1999/xlink
As dictated by [xname], the use of XLink elements and attributes requires declaration of the
What Is It?
XmlPull project is dedicated to be a site for
* for general Pull parsing promotion/education (including StAX) and in particular to contain easy-to-reuse samples and code fragments
* a resource for discussing new ideas and concepts related to pull parsing
* a java namespace (org.xmlpull.*) and project location of a free implementation of the event object API and Factories, based on the StAX XMLStreamReade and old Common API for XML Pull Parsing
* as java namespace and project location of StAX and XmlPull based utilities and samples
W3C XML Schema is one to specify the structure of and constraints on XML documents. As usage of W3C XML Schema has grown, certain usage patterns have become common and this article, the first in a series, will tackle various aspects of the creation and usage of W3C XML Schema. This article will focus on techniques for building schemas which are flexible and which allow for change in underlying data, the schema, or both in a modular manner.
Designing schemas that support data evolution is beneficial in situations where the structure of XML instances
W3C Schema can quickly become complex and difficult to determine if they are validating the correct vocabulary. The addition of embedded Schematron schema only makes this problem worse. Schema Unit Test (SUT) introduces a framework for testing XML Schema.
This framework has two parts.
The first is a namespace and vocabulary for embedding test cases into sample XML documents, designed to highlight what is legal and what is not legal in the vocabulary defined in the schema under test. This aspect is independent of what schema language is used and
