Problem

Some tbx structures are not supported for terminology import (so far), such as type="TBX-Core" style="dca". And in general TBXv3 so far is not supported.  When such a tbx is used for import into a term collection, the log will inform that the tbx did not contain any terms which is misleading

Solution

We should inform that the tbx structure is not supported.

Since TBX has many flavours, we should detect, if 

• the file contains all the tags, we expect a TBX file to have
• if it does NOT contain tags like conceptEntry, langSec and termSec, which are clear TBXv3 tags. And not a root-tag "tbx".
• It must contain a root-tag "martif".

If at least one of those criterias is NOT met, we should throw an error on import:

EN: The TBX version you try to import isx not supported. Please import a TBX v2-file (ISO 30042:2008).
