RESOLUTION: According to the current spec as clarified by the discussion 
on "immediately preceding" in the 2002 October 22 SG Comment document in 
response to comment 5 item 1 (see also email on the xsl-editors list [1]
for a public record of this response), the current situation is that the 
spaces in this example should not collapse.
