Problem

It should be possible to determine the exact spelling of a term in regard of lower/upper case. 

Solution

1. find and tag all terms regardless of upper/lower case, e.g. de "Sensor" and en "sensor" should tag text with de "SENSOR" and no term error given for usage of en "sensor" or usage of en "SENSOR".
2. however, if in text exact match for lower/upper case is found, here "Sensor", then exact target term "sensor" is expected, else an error is thrown (for en "SENSOR" e.g.)

Rule: exact casing match for term entry and source text -> exact target term casing required, else error

Scenario: If for SENSOR in source text capital letters in target are required, users need to maintain 2 term entries, one SENSOR - SENSOR and one Sensor - sensor

Exception: capitalization for term pretranslation for term-only segments:

term entry Sensor - sensor will be pretranslated in term-only segment with Sensor - Sensor. Here exact match is found, within a phrase "Sensor" will throw an error but in term-only segment it should not.
