Windows OK, Linux Fail:

I tried in a linux shell "ls not-existing/.." and if fails, while in a 
windows cmd prompt "dir not-exist\.." list the contents of "." - That 
may explain the first case.

I notice in the last line of the second case a *doubling* of what is 
very likely the value of $exist:controller ("/controller_test"), isnt it?

I guess that the "/xml" that shows up both times comes from the request. 
You have to get rid of this, because ".." will fail, as soon as you 
request "/xml/y/z.html" anyways. So absolute path-names is the way to go 
IMO. In a controller, I anchor style paths at "concat($exist:root, 
$exist:controller)", but I also have xq and xslt in the db, not the 
filesystem.

Did you try to output just what test.xq produces without an 
xsl-transform? If that works equally on both systems, then possibly, its 
only the xslt servlet, that interprets path differently?

I also found it very useful to see what the automatic values are:
         <dummy>
             <v>exist:root: {$exist:root}</v>
             <v>exist:prefix: {$exist:prefix}</v>
             <v>exist:controller: {$exist:controller}</v>
             <v>exist:path: {$exist:path}</v>
             <v>exist:resource: {$exist:resource}</v>
         </dummy>
They should be the same on both windows and linux.

HTH

PS: you can increase the performance of the process by using
1)  <set-attribute name="xquery.attribute" value="model"/>
2)  <set-attribute name="xslt.input" value="model"/>
in the respective forwards.
