Description Michael Kay 2005-05-02 07:48:28 UTC 
string($x) where $x is negative zero returns "0" in XPath 1.0, "-0" in XPath 2.0.

This should either be changed to make it backwards compatible, or the change
should be added to the backwards compatibility appendix.

Comment 1 Michael Rys 2005-05-02 13:49:11 UTC 
Since fn:string(-0e0) results in the same value as xs:string(-0e0), and having 
special semantics for this one case seems less desirable, we should document 
the difference in the backwards-compat appendix (and maybe make it part of the 
XPath 1.0 compat mode).
Comment 2 Don Chamberlin 2005-05-05 00:25:54 UTC 
Assigned to Michael Kay as editor of the XPath 1.0 Backward Compatability 
Appendix.
Comment 3 Michael Kay 2005-05-17 14:01:33 UTC 
This will be documented as an incompatibility in the XPath appendix.
