<br />
While the current version of the TCI contains crude read access (through a text conversion) that might be acceptable (but not comfortable to use) for TCI-TL or analysis of in template parameters of external functions is xTRI, it is not usable for building templates outside of the TE. Thus it e.g. not possible to modify out/inout template parameters in external functions or set the content of template parameters of test cases in TCI-TM (unless they contain no matching mechanism).<br />
<br />
This CR attempts to change that, introducing a new set of dedicated abstract TCI data classes and modifying the existing ones that allow the users to work with TTCN-3 templates in TCI without any restriction.</td></tr><tr class="print"><td class="print-category">Steps To Reproduce</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Additional

				I think I understand what you mean. In the current specification, there are only two ways on how to set a value to omit: either using RecordValue.setFieldOmitted or creating a blank new value by calling Type.newInstance.<br />
<br />
Introducing a new matching symbol for top-level omit is possible in general. However, before we decide in its favor, we should consider the consequences. The main problem is that such a matching symbol is not compatible with the representation of omit assigned to record fields. There are two possible ways to resolve this problem:<br />
<br />
1. Introduce the dedicated matching symbol and a rule saying that assigning MatchingMechanism(OMIT) to an optional field of a record value (by calling RecordValue.setField) is the same as calling RecordValue.setFieldOmitted for the same field.<br />
<br />
2. No new matching symbol and allow to explicitly create omit from existing instances by a new function Value.setNotPresent. The function would control the Value.notPresent property which is currently available only for reading.<br />
<br />
Which of the approaches would you prefer?<br />
