Re: <check> Response Attribute
Ed,
What does "exist" and "not exist" actually mean in this context?
If the registry used a good [1] random number generator and modulo 2
arithmatic to generate the {0,1} return value of a boolean <check>,
or always returned the value {0}, or always returned the value {1},
regardless of the operands, could a registry detect which algorithm
{random, always false, always true} was used?
I probably misunderstand what registrars do, and why, but if <check>
discloses some externally visible state(s), how is it externalized
from the registry, and how is it visible? Alternatively, is <check>
simply a means of expressing a protocol-visible consequence of the
application of a query or particularly a transform command upon an
object?
Next, what datatype is appropriate for the "reason why" portion of the
new <check> return?
Eric
