thank you for your proposition which is almost as good as David's, 
but which I personally find more difficult to follow. And it 
requires the stylesheet to explicitly state the element names, which 
might be a little inconvenient.

David's was neater but mine was more fully commented. :->

And actually, they were the same solution, or based on the same 
approach in effect, with only cosmetic differences.

While David's said "*", mine said "b|i|ul", but that too amounts to a 
cosmetic difference in this case. What's "a little inconvenient" in 
one case might be suitably clear or careful coding in another.

But anyway -- David's *was* nice....

What I meant was: Since I am using the "real" meta-stylesheet method 
(as opposed to how you characterized your proposal) to generate the 
stylesheet which is doing the WordprocessingML transformation, I 
prefer to make the style transformation configurable, by specifying 
the element equivalents of the styles as well as their nesting in an 
external XML document with a structure that could look like the one I showed:


So it's certainly somehow hard-wired in XML, but not necessarily in XSL.
Now I have become aware that this opens two ways:

1) Being totally dynamic, i.e. reading in the mapping and hierarchy 
description at the operating stylesheet's run time. This is what 
David's method does.

2) Being dynamic only in the first step, i.e. generating an 
operating stylesheet with the style mapping coded in it. This is one 
aspect of Wendell's solution.

I'll try to experiment with both to find the approach which is more 
favorable. (And I will have to refine the mapping technique to 
account for more complex cases than local name identity.)

Now you've got me even more confused.

What I said was that my approach did *not* use a stylesheet to 
generate a stylesheet.

Neither does David's.

And as I said, they were the same solution, allowing for these two 
things to be the same:

<xsl:template match="x">
    <xsl:when test="$cond">

<xsl:template match="x">
  <xsl:variable name="out">
    <xsl:when test="$cond">
        <xsl:copy-of select="$out"/>
      <xsl:copy-of select="$out"/>

... except that A (what David did) is a bit more concise, and B (what 
I did) is a bit more versatile (since you can do things like test 
what's inside $out when you do the test).
