qt-2004Feb1159-01: Last Call comments on XQuery 1.0: An XML Query Language XSCH-QL-016

Hi David and Per,

This is an official response from the W3C XML Query Working Group. It 
covers the following messages, each submitted by one of you:

We believe that implementors know how to test for circularity, and the
exact technique used may depend on their environment. For instance, in
an environment that does separate compilation of modules, they may
need to use linking techniques that are less straightforward than what
is needed in an environment that does not have this requirement.

We are concerned that it may be difficult to provide a definition that
works equally well in all environments and covers all of the cases. In
fact, earlier versions of our document once had such a definition, and
we found that discussion of various details of the definition took
significant Working Group time. We are inclined to simplify our lives
by assuming that implementors will be able to determine how to
implement this.

If, in the CR phase, we find that implementors have difficulty
detecting circularity, then we may add such a definition, and might
well start from the one that you provided.

Please let us know if you find this unacceptable.

Thanks,

Jonathan

On behalf of the W3C XML Query Working Group
