They are like variants. You can get a string as int or double, and you can get a double from a string or int (provided they convert sanely, otherwise you get 0). In addition, there are special things like string expressions (simple math operations) and color values (CSS-style) that can evaluate to an integer.

I recently read the doxygen documentation of MLT and I don't find anyway to retrieve the type of a property. You can get the number of properties, their names, their values but not their types. It is useful for automatically construct graphic interface from a service.

Is there a way to retrieve the type of a property ?
