[0] uncategorized [1] The issue has not been categorized. [2] A new version of a tool returns information on an issue that has not been previously checked and that is not yet classified. [3] S or T [4] 
This category has two uses: A tool can use it to pass through quality data from another tool in cases where the issues from the other tool are not classified (for example, a localization quality assurance tool interfaces with a third-party grammar checker). A tool's issues are not yet assigned to categories, and, until an updated assignment is made, they may be listed as uncategorized. In this case it is recommended that issues be assigned to appropriate categories as soon as possible since uncategorized does not foster interoperability.
