RE: grouping based on string but with child nodes

When we've looked at this kind of problem in the past, there have generally
been two styles of solution:

(a) convert the character-markup into XML-markup, then use structural
grouping

(b) convert the XML-markup into character-markup, then use
xsl:analyze-string

In this case (a) seems a better approach. First turn "||" into <newTitle/>
elements using analyze-string, then do a group-starting-with="newTitle".
