By escaping the namespace of the output XSLT instructions so the XSLT
engine doesn't get confused between what you are asking it to do and what
you are asking it to put to the result tree.

Without this mechanism, there would be no way to tell the difference
between an instruction to be acted on and an instruction to be emitted.

This escaping mechanism can be applied any number of times (stylesheets for
stylesheets for stylesheets etc.)

A terse example is below.

Note how the "xslo" namespace URI is prefaced with "quote:" which is
removed on output by the XSLT engine.  With it removed, it is recognized
the second time around.

I hope this helps.

p.s. please note that I changed "html" to be "hmtl" so that my mailer
wouldn't eat the markup and *help* me by displaying the HTML; the
principles of what I'm trying to show are unchanged.
