[xquery-talk] Re: about "module" in XQuery spec

[Michael Kay]

Then according to module's "independently undergo the static analysis phase"

definition, the answer will be "false" if implementation provide mechanism
to dynamically detect static unknow type(in order to fully support subtype
substitution),
and will throw an error if implementation did not provide such mechanism,
right? 

 
The specification doesn't say that implementations are obliged to throw an
error if the consistency constraints are violated. It says that the results
are undefined in these circumstances.
