Summary0007462: encvalue/decvalue should also work directly with octet and hex-string values
DescriptionAt the moment, any octetstring that should be encoded with encvalue or decoded with decvalue needs to be explicitly converted to bitstring.

This makes no sense in the most common case that the protocol is byte-based and in the adaptation layer, the bitstring again has to be converted to bytes, creating a possible imperformance.

Therefore, we propose to allow encvalue and decvalue to also work directly with octetstrings (and hexstrings).
Additional InformationSince the encvalue function at the moment returns a bitstring, it's semantic description might be a little more problematic as the return type would be determined from the demanded type of the encvalue() function call (i.e. the variable it is assigned or parameter type it is used as actual paramter for).

Only in context-less environments (log, setverdict, testcase.stop, comparison operators where both operands are of indeterminate type), the bitstring-default-result type would be used for backward compatibility reasons.

Alternatively, two new predefined functions encvalue_octetstr/decvalue_octetstr could be introduced. That doesn't make the TTCN-3 code shorter, but at least no unnecessary conversions need to take place.

 the CR7462-V2.docx seems to contain several problems:
- C.5.2 calls the function "encvalue_o" in the example, but decvalue_o in the text.
- also in both cases the text talks about working with octetstrings, but the examples display bitstring returns and parameters
