I appreciate your response and the fact you leave something to be
figured out. Admittedly I am very new to XSLT (less than 2 weeks) and
have a lot to learn. This problem in particular was escaping me and, to
boot, frustrating me as I am running up against my deadline. However, I
have finally got it right (just this second) and I now have a greater
understanding of what I was missing. I had changed so many things over
time I had lost track of what I had and hadn't tried. Most of my
confusion was around the match and grouping functionality adn the thing
that finaly bit me in the end was missing the copy-of, which was
present in your sample.
Anyway, thanks helping me to stretch my learning. I do have one
performance/maintainability question if you don't mind. I am wondering
about the is-inline method. In particular the "or" condition for
building the sequence of in-line elements. Is this the best way to
manage the list of included elements. I am wondering if it is a
performance issue. I am wondering if there is a better way to capture
the list of inline elements. Maybe in a global variable?
FYI - Here is the working and complete version of the script. It seems
so straight forward now. Thanks again.

Sorry to keep asking about this problem but I am still having
issues.
The change you mention below does remove the error but now it never
hits the block of code to wrap the elements in the textnode. It is
simply outputting the input verbatim.
I'm afraid that when I reply to a question, I supply snippets of code
that
address the issue you're having, but don't attempt to supply a
complete
working solution: I leave that to you. Usually I reckon that this
forces
people to understand the solution rather than just transcribing it,
which
means they will learn more and have less need to return for further
help...
Looking at your code, you're inside a template with match="/", so
select="node()" is only going to select the outermost element, and
grouping
a single element is not very useful. You need to put this code in the
template rule for the element that contains the nodes to be grouped.
You may
also need to apply it at more than one level, in which case the
xsl:copy-of
should be replaced by an xsl:apply-templates.
