I personally never really got a good handle on this issue, but I don't think
it is serious.  I think there was a change in philosophy at php.net and they
planned to remove call-time-pass-by-reference, but then brought it back in
again in later versions.

What version of PHP are you using, and what version of Php.XPath are you
using?  I'm using 4.1.1 (Win32) and have allow_call_time_pass_reference set
to on.  And my production server is 4.2.3 (Linux) and also has
allow_call_time_pass_reference set to on.

Hope this is of some help, and if were lucky someone else on the list will
clarify for the both of us... :o)
