translate5 supports SDLXLIFF as import format.
SDL Comments
Comments on segment level can be imported if enabled in the config (set runtimeOptions.import.sdlxliff.importComments to 1, more information about configuration), otherwise an error occurs on import if the file contains comments.
Target comments: if there are comments on specific words only, they are converted to comments pointing to the whole segment. This changes to the comments are persisted to the SDLXLIFF file on export.
Source comments are imported too. Single words comments remain here, since the source content can not be changed.
SDL change-marks
Change marks can automatically be applied to the content and removed from the import file by setting runtimeOptions.import.sdlxliff.applyChangeMarks to 1.
Since the changes are applied to the content, the whole change-mark information is removed from the SDLXLIFF file, change-mark meta information (like time of change and author of a specific change) is getting lost.
Track changes
The SDLXLIFF-syntax for the "track changes" functionality is supported in the export.
