Initial Comment:
Hi Sedna Team,

Bug description:
When there is an XQuery declaration, blank lines and or/comment lines
(a total of N lines) preceding the query body and there is a syntax or
static analysis error in the query body, the Semantic Analyser reports
the incorrect line number for the error. It appears that the reported
line number of the error is N less than it should be.
This bug makes it difficult to find errors in one's XQuery source code.
Two modules provided here, a.xqlib and b.xqlib, contain exactly the same
error but at a different line number dues to different number of header
lines before the query body. When LOAD OR REPLACE MODULE with these
the error indicated at line 5, position 5 which is incorrect. The
correct location of the error in these files is at (13:5) and (20:5)
respectively. (Reproduce by running attached shell script, fault.sh)
Also note that Sedna does not report the file name of the offending
module so this makes locating the error more difficult as well.
SEDNA Message: ERROR XPST0081
It is a static error if a QName used in a query contains a namespace prefix
that cannot be expanded into a namespace URI by using the statically known
namespaces.
Details: at (5:5), prefix 'math' has not been defined

Bug resolution:
Sedna should indicate the BOTH file name AND correct line number of
any reported errors.
Attached:
a.xqlib, b.xqlib, fault.xq, fault.sh
Regards
Justin Johansson
