>
> Currently the {{PropertyState}} contract specifies that an
> {{IllegalStateException}} gets thrown if a single-valued property is accessed
> as a multi-valued one (and vice versa).
> This leads to cumbersome if statements in code that simply wants to go
> through all the values of a property. To avoid that complexity it would be
> useful if, instead of throwing an exception, the {{getValues()}} method
> simply returned an iterable containing the one value of a single-valued
> property. A client that wants to explicitly check that a property really is
> multi-valued can still do so simply enough by calling the {{isArray()} method.
> A somewhat similar case can be made also for {{getValue()}} on a multi-valued
> property, but that's a bit trickier so let's leave it outside the scope of
> this issue.
