problem

If locked tags are moved and the sdlxliff is exported then with change marks enabled, such construction is produced:

<add><lock xid=123></add> text <del><lock xid=123></del>

now the xid is duplicated which leads to invalid (non importable) SDLXLIFF.

solution

change the currently implemented algorithm of TRANSLATE-3420 in the following way:

Collect all duplicated locked tags, regardless if in source or target. Clone the referenced transunit with a new id, and use that id as xid in the locked tag.

This approach was tested with the non working export if TS-3231 and was then importable in Trados.

Contact Sasha about how to embed that in the SDLXLIFF tests.
