What is the difference between xsd and xs

The sequence group specifies that all the elements defined in this group must appear once in the XML document. These elements must appear in a specific order. A sequence group can contain other groups as well as elements. InterConnect creates an element for a sequence group. If the value of maxOccurs for a sequence group is greater than one, then the object of this sequence group is created as an array in InterConnect.

The All group specifies that all the elements defined in this group must appear once in the XML document. These elements can appear in any order in the XML document. The All group cannot contain other groups.

InterConnect creates a element for the All group. If the value of maxOccurs is greater than one, then the object of this All group is created as an array in InterConnect. XSD namespace is a collection of element and attribute names and their types. Namespaces are associated with a prefix when they are declared, and this prefix is used along with a local name to represent an element in an XML document.

For example, Book:Title where Book is the namespace prefix and Title is name of the element. XSD namespace provides a way to distinguish between duplicate elements, attribute names and their types. Target namespace defined in a schema specifies the namespace where all the global elements and attributes defined in schema reside. When an element in XSD does not have a named namespace, it means that this element belongs to the NoNamespace namespace. You can divide an XSD into parts so that it is easier to maintain and read.

You can use the xsd:include and xsd:import statements to use the content of one XSD file in another. The include statement is for schemas that exist in the same target namespace or do not have a defined target namespace. The import statement is for schemas that exist in another target namespace. InterConnect first resolves the schema that is being imported. All references to the types and elements of the schema being imported or included are replaced by their definitions.

Following are the three points at which a message is validated during its flow in InterConnect:. This validation is performed against the publishing application view XSD. Figure displays the Validate XML option as selected. This validation is performed against the common view XSD. After InterConnect transforms a message from common view to application view: This validation is performed against the subscribing application view XSD. You can derive new complexTypes data types by extending or restricting existing simpleTypes or complexType data types.

Extension means taking an existing type as the base and creating a new type by adding to its content. Definition of the base complexType data type is included in the definition of new complexType data type.

You can add new elements and attributes to new complexType data type. When you import an XSD in InterConnect, the schema parser parses the schema and gives the resolved schema model. The resolved schema model resolves the type definitions by copying the definition of derived types to deriving type and adding the new elements and attributes to it. You can derive a complexType data type by restricting a base complexType data type.

Restriction is type definition whose declarations are in a one-to-one relation with another specified type definition. A complexType type derived by restriction is very similar to its base type, except that its declarations are more restricted than the corresponding declarations in the base type. All the components of the base type that are to be included in the derived type must be repeated in the derived type definition.

When you derive a new type by restriction, the definition of derived types is not copied to the deriving type. InterConnect stores the definition which is being used by the elements in the hierarchy of the selected root element.

Also, certain features of XSD have some limitations. This section describes the following topics:. In an XML instance, if you specify the xsi:type attribute, then the derived types by extension or restriction appear at the locations where the base type element is expected. InterConnet does not support the xsi:type attribute and assumes that the element is of the original type. In a model group definition, if an any element is not located at the end of a sequence, then InterConnect throws an error.

Any ComplexType element having only one single element, which is an any element, is assumed as a String by InterConnect. An element and an attribute contained in the an element cannot have the same name. Skip Headers. Nillable Sometimes, you need to represent unknown information, or inapplicable information, explicitly with an element. Viewed 62k times. Improve this question. Add a comment. Active Oldest Votes. The important is how you declare the namespace.

For example, consider this style resource:. The second key difference is that some attributes only affect views if they are defined in that view's theme. Just like the first rule said, styles containing theme attributes will apply to all children of the view with the android:theme attribute.

Instead, declare only the local name plugin and handle the namespace prefix declaration at the XSD level What is the difference between xsd and xsi? Asked 4 Months ago Answers: 5 Viewed times.
