These extensions are required for Compliance Report generation. Depending on what "standard" you are targeting in your Compliance Report, you can install a combination of extensions:

• To generate Compliance Reports for MIPS standards, you MUST always install the MIPS Reduction Index extension.
• To generate Compliance Reports for CISQ, ISO-5055 and Security standards, you can install either the CISQ, ISO-5055 and Security Standards extensions or the Quality Standards Mapping extension. If the CISQ, ISO-5055 and Security Standards extensions and the Quality Standards Mapping extension are installed, data is automatically taken from the CISQ, ISO-5055 and Security Standards extensions at all times.
