XSR objects

The XML schema repository (XSR) supports the creation of a copy of the information contained in an XML schema, DTD or external entity as an XSR object. This information is used to validate and process XML instance documents stored in XML columns.

New XSR objects must be explicitly added to the XSR before use through the registration process, which identifies the XML schema, DTD or external entity. XSR objects can be registered from Java applications, stored procedures, or the command line processor.

The most widely used XSR object is the XML schema. Each XML schema in the XSR can consist of one or more XML schema documents. Where an XML schema consists of multiple documents, the document used to begin the registration process is the primary XML schema document. Where an XML schema consists of only one document, that document is the primary XML schema document.
