The schemas are defined in .rsd configuration files. These files have a simple format that makes them easy to extend; for example, to gain more control over custom fields.

To save a schema to an .rsd file, call the CreateSchema stored procedure; for example, with the IncludeCustomFields connection property set.

To use custom schemas, set the Location property to the folder containing the .rsd files. The schemas included with the provider are located in the db subfolder of the installation folder.
