The new version of xmlservice 1.9.9.2 (+), supports pass by value. See the commits for how to use.

Correct answer: The new version xjservice (json version) plan support 'value' or 'const' (Common 2017).

Hack answer: However, most people do not know that anything > 16 byte 'const' or 'value is actually passed by reference anyway (compiler copy passed by ref). That is to say, xmlservice does not support by value for 1-16 bytes values. Unfortunately any packed or zoned by value will fit in 16 bytes (exotic types by value fit 2 registers <= 16 bytes). While 'glass half full', may help some people with 'value' or 'const' > 16 bytes. See this link Yips value - not what you think.

Yep. Pass by value is not tested. 99.8% of all RPG programs pass by reference, therefore, a place holder was added, but never really tested completely. We will put it on the list.

For now, you are much better off simply staying with pass-by-reference, aka, forget const correctness, nobody does it anyway, except the real geeks. BTW -- you could wrap your API in by refernce and call by value on your own as well.
