NOTE: For each IPDR schema directory, there are two files. The file that uses semantic versioning in the file name (e.g., DOCSIS-CM_3.7-A.4.0.0.xsd) should be used for implementation. The file without versioning in the file name (e.g., DOCSIS-CM.xsd) should not be used for implementation, but it will be maintained to always match the most recent versioned file.
