+/*
+ * This is not a full implementation of a field type, but adds some
+ * support for higher level languages with some restrictions to interop
+ * with C language. Especially the collection of arguments for the
+ * various fieldtypes is not based on the vararg C mechanism, but on a
+ * iterator based callback mechanism that allowes the high level language
+ * to provide the arguments as a structure. Most languages have mechanisms
+ * to layout structures so that they can be passed to C.
+ * The languages can register a new generic fieldtype dynamically and store
+ * a handle (key) to the calling object as an argument. Together with that
+ * it can register a freearg callback, so that the high level language
+ * remains in control of the memory management of the arguments they pass.
+ * The design idea is, that the high-level language - typically a OO
+ * language like C# or Java, uses it's own dispatching mechanisms
+ * (polymorphism) to call the proper check routines responsible for the
+ * argument type. So these language implement typically only one generic
+ * fieldtype they register with the forms library using this call.
+ *
+ * For that purpose we have extended the fieldtype struc by a new element
+ * that gets the arguments from a single struct passed by the caller.
