Associating a Schema to XML Documents

Oxygen XML Developer relies on schemas to validate XML documents and to compute valid proposals for the Content Completion Assistant.

Supported Types of Schema

The following schema types are supported:

W3C XML Schema 1.0 and 1.1 (with and without embedded Schematron rules)
DTD
Relax NG - XML syntax (with and without embedded Schematron rules)
Relax NG - compact syntax
NVDL
Schematron (both ISO Schematron and Schematron 1.5)

Detecting a Schema

For the purposes of using validation and content completion mechanisms, Oxygen XML Developer tries to detect a schema by searching multiple locations, in the following order:

The schema defined in a validation scenario.
The schema defined in the validation scenarios associated with the particular document type (if defined).
The schema that is associated directly in the XML document.
The schema defined in the framework (document type) configuration.

In addition, the locations of the schema can be mapped through the use of an XML Catalog. For more information, see Resolving Schema Locations Through XML Catalogs.

Tip: To quickly open the schema used for validating the current document, select the

Open Associated Schema action from the toolbar (or Document > Schema menu).
