W3C XML Schema is complex and hard to learn, although that is partially because it tries to do more than mere validation (see PSVI). Although being written in XML is an advantage, it is also a disadvantage in some ways. The W3C XML Schema language, in particular, can be quite verbose, while a DTD can be terse and relatively easily editable.
This is a list of notable XML schemas in use on the Internet sorted by purpose. XML schemas can be used to create XML documents for a wide range of purposes such as syndication, general exchange, and storage of data in a standard format.
The problems users face when working with the XSD standard can be mitigated with the use of graphical editing tools. Although any text-based editor can be used to edit an XML Schema, a graphical editor offers advantages; allowing the structure of the document to be viewed graphically and edited with validation support, entry helpers and other useful features.
XML Schema, published as a W3C recommendation in May 2001, [2] is one of several XML schema languages. It was the first separate schema language for XML to achieve Recommendation status by the W3C.
[4] [5] Version 4.1, released in 2001, added the capability to create XML schemas. [6] The 5.0 version of the program was released in 2002, adding a XSLT processor, XSLT debugger, a WSDL editor, HTML importer, and a Java as well as C++ generator. The version's XML document editor was redesigned to allow for easier use by businesses. [7]
XML Signature defines syntax and processing rules for creating digital signatures on XML content. XML Encryption defines syntax and processing rules for encrypting XML content. XML model (Part 11: Schema Association of ISO/IEC 19757 – DSDL) defines a means of associating any xml document with any of the schema types mentioned above.
June 2002 Stylus Studio 2004 released a two way visual schema designer for XML Schema 1.0 and the first IDE to feature postmortem stack trace for XSLT with back mapping to the XSLT source. At that time it was the only XSLT debugger supporting cross-debugging between XSLT and Java extension functions.
Element substitution techniques allow the substitution of new XML Schema elements, representing derived NIEM properties that can be used where the parent properties are expected. There are three XML Schema techniques that support the NIEM use of element substitutions: use of substitution groups; creation of abstract, type-less elements, and
