Problem

The internal-tag check does not repair & find tag-errors, that refer to tags in trans-units consisting of multiple segments.

Challenges

• Paired tags spanning several segmets of a trans-unit will end up as <it> - tags with the attripute pos="<open|close>". Currently those are seen as singular tags and thus errors cannot be detected
• When the import without framing tags is active, the counterparts possibly end up in the skeleton-file making a potential check further complicated

Solution

• To avoid this, we will not allow the removal of <it>-tags representing an opening/closing tag of a tag-pair
• In the frontend, the tag-check must check for such tags and raise an error, if such tags are removed and prevent saving of such segments (even, if tag-removal is generally allowed!).
