Am trying to understand the on-the-fly validaiton
behavior. Am afraid I may get Validation exceptions
when I am in the middle of constructing the Instance.
Let's add some Key constraints to the schema. Now,
will get an Validation exception if I were to complete
the definition of the Key (say, made up of 4 elements)
at different times (meaning I may not define all at
once but definitely before the exit from app). How
would one let know the on-the-fly validator about this
so that we don't get premature exceptions?
In other words, Is it that you need to take lot of
precautions while doing this live validatio (like
adding dummy root closing tag,etc)?
