Step 4: Associate the Schema to the Framework

In the bottom section of the Document Type configuration dialog box, there are a series of tabs. The Schema tab refers to the schema that is used for validation of the documents that match the defined association rules.

Important: If the document references a schema directly (for example, using a DOCTYPE declaration, xsi:schemaLocation attribute, or a Relax NG xml-model processing instruction), the schema defined in this Schema tab is not used for validation or content completion.
Schema Type

Select from the combo box the value XML Schema.

Schema URI
Enter the value of the schema location (for example, ${framework}/schema/sdf.xsd). Use the ${frameworks} editor variable in the schema URI path instead of a full path to be valid for multiple Oxygen XML Author Eclipse plugin installations.
Important: The ${frameworks} variable is expanded at the time of validation into the absolute location of the directory containing the framework.
