If you provide a converter, they you can have ParameterizedCommands that
have parameters of different types. The underlying restriction is the
parameters must be able to be converted from Object -> String -> Object.
The types are defined in the org.eclipse.ui.commands extension point,
and although they can be specified in Eclipse4 RCP apps, they can't be
defined yet from the model. See
org.eclipse.ui.internal.commands.CommandPersistence.readParameterTypesFromRegistry(IConfigurationElement[],
int, CommandManager) for an example of where they're defined while
running the 4.x Workbench. For how they're currently defined, see
org.eclipse.ui.commands [1]. It should be possible to define your own
commandParameterType programmatically once the CommandManager is available.
