We have a usecase where in we will have to convert the file extension from filename.xml/filename.dita (topic file) to filename.custom (custom extension) when we send it to TMS via translation connector. And we wanted to convert it back to filename.xml/filename.dita DITA topic post translation.
Yes, we wanted to change topicfile.ditamap to topicfile.xml as TMS use XML settings for ditamaps and dita import setting for topic files within the single project. We would like to send both ditamap and topic files to be sent at the same time using single project settings in TMS( and able to differentiate two files). Hope this clarifies
