preceding-sibling on sorted nodes

preceding sibling sorted
When sorting using XT the preceding-sibling axis seems to operate on the
nodes in source tree order not in sorted order.  Is this correct behavior?
I couldn't tell from the spec.

I'm not sure how to workaround this, since I'm trying to do grouping after
sorting and using preceding-sibling is the only way I know of to do
grouping.  If there are prior threads on this issue please say so, I could
find anything in the last few weeks.

thanks!
