(For Developers, By Developers)
The XML Schema NMM (Non-Markup Model) is a specific language used to describe the data elements of an XML document. The root element is the main point of reference that defines the entire document and must be uniquely identified by its type.
What is the root element?
The root element is the main point of reference for an XML document. It is the first element declared in an XML document, and all other elements must be nested within the root element. The root element must have a unique type identifier, and all elements must use the same namespace.
What is the root element of a W3C XML Schema NMM?
The root element of a W3C XML Schema NMM is <schema>. Specifically, this element is used to define all other elements of the XML document. It must use the http://www.w3.org/2001/XMLSchema namespace, the schema language version (e.g., version="...4.0") and other important attributes.
What does the <schema> element do?
The <schema> element is the "foundation" for all elements of the XML document and sets the namespace for the schema language. It defines the structure, type, elements, and content-related rules of the document. This element serves as the base reference for the entire XML document and all elements must be nested within it.
What impact does a <schema> element have?
The <schema> element is of critical importance, as it serves as the basis for the entire document and ensures that all elements can be validated against a set of rules established by the schema language. Without the <schema> element, the XML document can still be parsed by most processors, but it will be unable to meet any of the schema language requirements.
