Re: paths starting with "//" are invariant?

I just figured it out, i think.

in the second occurence, i was inside a template which was applied to the
result of a xt:node-set call. 
apparently such results have a different document root, so paths with
"//" don't match any more, usage of id() fails, and so on.

I can't say this is a bug, since this is a non-standard extension after all.
saxon has the same, er, feature.

I haven't figured out how to do the equivalent of xt:node-set() with
xalan/lotusxsl yet (suggestions anyone?), so i can't say what it does.

i can say that result tree fragments continue to ruin my life :).
