Schema Settings

In the dialog for editing the document type properties, in the bottom section there are a series of tabs. The first one refers to the schema that is used for validation of the documents that match the defined Association Rules.

Important:

If the document refers a schema, using for instance a DOCTYPE declaration or a xsi:schemaLocation attribute, the schema from the document type association will not be used when validating.

Schema Type

Select from the combo box the value XML Schema.

Schema URI
Enter the value ${frameworks}/sdf/schema/sdf.xsd. We should use the ${frameworks} editor variable in the schema URI path instead of a full path in order to be valid for different Oxygen XML Author installations.
Important:

The ${frameworks} variable is expanded at the validation time into the absolute location of the directory containing the frameworks.
