This case-sensitive code system `http://cql.hl7.org/CodeSystem/cql-message-source-codes` defines the following codes:

Code | Display | Definition
content | Content | The message is associated with content, such as input values. Content messages can typically be addressed by correcting the input value.
application | Application | The message is associated with the application, such as an unexpected situation in application processing. Application messages typically need to be addressed by the application developer.
system | System | The message is associated with the system or infrastructure, such as internal translator or engine errors. System messages typically need to be addressed by infrastructure developers.
environment | Environment | The message is associated with the overall operating environment, such as network timeouts, or memory or disk space issues. Environment messages typically need to be addressed by a system administrator.
