  Sorry for responding now, but I wasn't really able to follow XSL List
until today.  So what you want is grouping.  The key is
text()[contains(., '&_#10;')].  Nodes are copied, but the key that is
cut on the new line char.  I assume there is maximum one new line char
in a text node.

  You have to check if the first node in each group is a text node that
contains a new line: in the first group, it can be something else.  You
have also, in all but the last group, to use the substring before the
new line in the next text node.

  You can also check if you are in a group where the only node is a
text node containing a new line, but nothing after the new line, to
prevent generating empty para elements.  You can use normalize-space()
also here.
