XLIFF files for AtoM that have been converted so the style of the XLIFF is the same as the style Weblate produces.
Each non-master branch should correspond to an AtoM version. Switch to, or create, the appropriate branch for the AtoM major version being worked with.
Branch name example: 2.5.x
Scripts that can change XLIFF style to and from Weblate's style (versus AtoM's style) live here:
