Dear developers,

If I run the follwoing XQuery query with Galax:

==========
test.xq
==========
declare namespace t = "test";

declare function t:echoVoid() { () };
t:echoVoid()
==========

Galax gives a warning:

$ galax-run ~/test.xq 
[WARNING] 
Expression '???' at File "/ufs/zhang/test.xq", line 3, characters 8-37
has empty type, but is not the empty expression

()

Does any one have an idea how I can correct/modify my query to get rid
of this warning?


Thanks in advance!

Jennie
