In several places in the UML spec, we find the following expression
What are the leading _ and ' ' doing there.
For example, on page 310 we have.
body: ownedParameter->select(direction=ParameterDirectionKind::_'in' or direction=ParameterDirectionKind::inout)
See that the inout literal does not require _ or the quotes.
This appears to happen with all OCL mentions of the "in" literal
