By throwing away all the interior markup and using normalize-space

If anyone from the WG is reading this they might like to explain how
(if:-) the xpath2 deep-equal function would (or wouldn't) help here.
the following modifies things so that the <note> element geths through
to the output, but whether its notion of equality agrees with your own
I'm not sure...
I don't think it really does test _equality_ in real-world
xml-as-document cases, since without normalize-space
a single whitespace (of any sort) in the <app> in between
<rdg>s, or in them, causes two otherwise equal readings
not to be merged into one. Yes, I can see that this could mean
they aren't technically identical, but certainly for my purposes
they would be equal. i.e.:
------
<p id="a2"><body wit="A B C">This is a
<app><rdg wit="A">test</rdg>
<rdg wit="B"><note>Test</note> testament
</rdg>
<rdg wit="C"><note>Test</note> testament </rdg>
</app> only a test.
</body>
<body wit="D">This is a different body element</body>
</p>
------
Should output:
<p id="a2">
<body wit="A">This is a test only a test.</body>
<body wit="B C">This is a <note>Test</note> testament only a test.</body>
<body wit="D">This is a different body element</body>
</p>
------
I know B and C are different since B has a newline and C some spaces,
but it still strikes me that this should be possible?
Would another approach be to expand all the <rdg>s in a first
stylesheet, normalizing-space (somehow?), and getting something
like:
------
<p id="a2">
<body wit="A">This is a test only a test.</body>
<body wit="B C">This is a <note>Test</note> testament only a test.</body>
<body wit="C">This is a <note>Test</note> testament only a test.</body>
<body wit="D">This is a different body element</body>
</p>
------
Before passing through another stylesheet which does the
comparison/merge? Or am I barking (up the wrong tree)?
