Non trivial processes tend to have complex input parameters, beans instead
of common "primitives"
(to be interpreted in a lax way, e.g., Date as a primitive too), such as
ranges, lists of values.
I'm tempted to just go the way to suggest though, it covers a good number
of use cases and it's
the easiest way for the user to deal with.
Maybe in WPS land we can also use the PPIOs as tentative converters, in any
case a complex bean
needs to be de-serialized from string/xml/json somehow.
Geotools wise one could write a custom converter, although that seems a
quite a bit heavy handed
way to just have a mean of declaring a default value...
