    17         I'm instance of function and I'm holded in interprete's

    18         funcTable. I know my name as well as namespace uri in which

    19         I'm. 

    20 

    21         To execute myself on conrete data, you have to 'instantiate' myself

    22         using the #instantiate to obtain so called 'function instance'. Then

    23         you have to fill the instance with particular content (as parameters,

    24         interpreter and so on) and evaluate me (I'm actually a command pattern).

    25 

    26         I've two main subclasses - NativeFunction and UserDefinedFunction. Note,

    27         that NativeFunctions is his own 'function instance'.
