| Subject: | Registered functions cannot return supplied arguments anymore |
The attached script implements a simple registered function which just
returns the supplied argument. This used to work with XML::LibXSLT 1.62
and earlier versions, but stopped to work with change version 1.63
(specifically, it seems that the change
svn://axkit.org/XML-LibXSLT/trunk@194 is causing the problem). Note that
the sample again works if I slightly change the supplied argument, e.g.
putting it in "..." is sufficient.

Slaven
