That is also a possibility,
but than we have an other caveat.

If the value of the original field is valid and all other values are valid to, 
the data is ready to be written to the database or where ever. Ok so far.

But if you think of Date Element or an element with an Inflator we run into 
trubble as all that processing didn't take place and the application can 
retrieve the data it is expecting.

So we have to die one death, right? (OT: Can you say that in english?)


The solutions I can think of gets somewhat complex:

Make a copy of original input data.
When constraint complains and original input data was empty and some flag is 
set we just erase the value and don't show an error message.

But we might get more 'why slow' questions on the ML.

Greets,
