Some examination of
http://www.xmlsoft.org/XSLT/tutorial/libxslttutorial.html
suggests that the parameter values need to be single-quoted,
and indeed when I change the last part of your example to

'n1=''v1'',n2=''v2'',n3=''v3'',n4=''v4'',n5=''v5'''::text);

I get

xslt_process
-----------------------
<samples> +
<sample>v1</sample>+
<sample>v2</sample>+
<sample>v3</sample>+
<sample>v4</sample>+
<sample>v5</sample>+
</samples> +

(1 row)

So this seems to be a documentation problem more than a code problem.

(It's a bit distressing to notice that the regression tests for the
module fail to exercise 3-parameter xslt_process at all, though.)
