What is target namespace in XSD?
The targetNamespace declares a namespace for other xml and xsd documents to refer to this schema. The target prefix in this case refers to the same namespace and you would use it within this schema definition to reference other elements, attributes, types, etc. also defined in this same schema definition.
What is namespace in XSD schema?
Namespaces are a mechanism for breaking up your schemas. Up until now we have assumed that you only have a single schema file containing all your element definitions, but the XSD standard allows you to structure your XSD schemas by breaking them into multiple files.
What does XSD sequence mean?
What is XSI and XSD in XML?
The xsi prefix referring to the The Schema Instance Namespace http://www.w3.org/2001/XMLSchema-instance is used in XML document instances for several special attributes defined by the XML Schema Recommendation: xsi:type allows an XML instance to associate element type information directly rather than through an XSD.
What is the difference between namespace and targetNamespace in XML?
The targetNamespace is the unique namespace of that type, just like the package name of a class defintion is the unique namespace of that type. In other words, declaring a targetNamespace in an XML Schema is the same as declaring a package name in a Java class file. It assigns the type(s) to a particular namespace.
What is XSI in XML schema?
The prefix "xsi" is the namespace prefix used by convention for the XML Schema instance namespace. XML documents can contain elements that have an xsi:type attribute. This behavior provides an explicit data type for the element. The MRM XML parser in sensitive to xsi:type attributes in the XML document.

Does sequence matter in XML?
A sequence or choice may occur more than once. Choice is just one of a list of elements and sequence is a defined order of elements, 'all' is unordered. This is certainly useful in that it allows us to validate the syntax of an instance file but the order of the instance data is always deemed to be significant.
In this article
In writing XSD schemas, you can use the XSD targetNamespace attribute to specify a target namespace. This topic describes how the XSD targetNamespace, elementFormDefault, and attributeFormDefault attributes work, how they affect the XML instance that is generated, and how XPath queries are specified with namespaces.
A. Specifying a target namespace
The following XSD schema specifies a target namespace by using the xsd:targetNamespace attribute. The schema also sets the elementFormDefault and attributeFormDefault attribute values to "unqualified" (the default value for these attributes).
