Hi,

it’ll be my job to create formulars where the given information can be  
strutured. There’s not only value1=x, value2=y, value3=z, but also  
value1=x, value1\_a=y, value1\_b=z and so on. I’m asking myself whether  
it’s good to save those meta informationen in the formular data anyhow  
or to have a kind of parser, which structures the information given by  
the formular data on the basis of a predefined syntax definition and  
validates the incoming data with a state machine, for example. The  
problem is, I think, that a formular can easily be manipulated and  
thus an extra checking is necessary anyhow.

Thank you for any suggestions!
