 XML Schema - Wikipedia, the free encyclopedia
Converting an XML document to a datatype-aware object can be beneficial in some parts of computer software design, but critics contend that it also undermines openness, a key feature of XML, and that it is biased toward compatibility with the datatypes native to Microsoft's favored programming languages.
However, unlike most other schema languages, XML Schema was also designed with the intent of validation resulting in a collection of information adhering to specific datatypes, which can be useful in the development of XML document processing software, but which has also provoked criticism.
XML Schema, published as a W3C Recommendation in May 2001, is one of several XML schema languages.

 XML - Wikipedia, the free encyclopedia
XML's regular structure and strict parsing rules allow software designers to leave parsing to standard tools, and since XML provides a general, data model-oriented framework for the development of application-specific languages, software designers need only concentrate on the development of rules for their data, at relatively high levels of abstraction.
Although XML is fundamentally text-based, software quickly emerged to abstract it into other, richer formats, largely through the use of datatype-oriented schemas and object-oriented programming paradigms (in which the document is manipulated as an object).
Mapping XML to the relational or object oriented paradigms is often cumbersome.

 W3C XML Schema
XML Datatypes Library is a Java implementation of W3C XML Schema Part 2.
XML Schema Quality Checker (SQC) is a program which takes as input documents containing XML Schemas written in the W3C XML schema language and diagnoses improper uses of the schema language.
Schema processing is available only in the commercial version of the Saxon product, which is available for a free 30-day evaluation.

 Ian Stuart's personal web site - XML Schema, a brief introduction
XML namespaces differ from the "namespaces" conventionally used in computing disciplines in that the XML version has internal structure and is not, mathematically speaking, a set.
We envision applications of Extensible Markup Language (XML) where a single XML document may contain elements and attributes (here referred to as a "markup vocabulary") that are defined for and used by multiple software modules.
This is a piece of example XML code.

 Real-world XML Schema
XML and the XML Schema language were designed as general solutions that include facilities for almost every need.
However, even when such an optimal schema is possible, you may want to let the application deal with some bad messages (such as when valid values change too dynamically for enumeration in a standardized schema).
As a result, validation of messages with XML schemas does not eliminate the need for applications to verify that input data is acceptable.

 XML Schema FAQ
JaxMe is a source code generator that takes an XML Schema document as input and generates Java sources for working with compliant instances, including a SAX 2 ContentHandler.
XML Schema provides powerful dedicated validation features for things like uniqueness, referential integrity, enumerations, complex types and the various datatype facets, but it doesn't support arbitrary validation logic.
Apart from the trivial sense of supplying the values of fixed attributes, there is a proposal to map XML Schemas to ASN.1 - this covers mappings of both schemas and instances, and would permit the use of existing ASN.1 technologies for signing and compressing messages.

 Practical XML Schema
XML exists in two versions: 1.0 defined in 1998 and 1.1 defined in 2004.
XML 1.1 adds very little to 1.0: support for defining elements and attributes in languages such as Mongolian or Burmese, support for IBM mainframe end-of-line characters, and almost nothing else.
The XML Schema language more closely resembles the way a database describes data.

 XML Schema
Thus, anyone planning to rely on the Schema for Schemas should be aware that the possibility exists that a change of this sort might be made in the future.
As of version 2.2.1, it is hoped that Xerces-J will always be able to parse the Schema for Schemas current at the time of the product's release.
As of version 2.2.1, this implies inserting special logic to permit the presence of the built-in Schema datatypes in this particular schema; an issue has been raised with the Schema Working Group, in hopes the document will be modified so that the built-in types are no longer presented as global components.
