Reports Configuration File Schema
New custom report types can be added to Microsoft CRM through the reports configuration file. For each new report type, a "viewer" can be defined which specifies the report type's filename extension and a handler which can display a report of the given type.
The schema for the reports configuration file is shown below. A copy of this schema can be found at C:\Inetpub\wwwroot\_Resources\reports.config.xsd for a default Microsoft CRM 3.0 installation. A sample reports configuration file is shown following the schema.
