Re: elements in a namespace

Hmm which makes it rather inconvenient to take a stylesheet that works
with instances of an XML DTD if those instances are then embedded into a
larger document using a namespace based mechanism.

eg I might have (in fact I have:-) stylesheets for MathML that all look
like

<xsl:template match="apply/diff" .....

If it ends up that MathML gets embedded into some larger scheme such as
docbook (or even html) via a namespace which might be of the form
say
 <math xmlns="http://www.w3.org/Math/MathML/1.0">
      <apply>
        <diff/>
... (I just made that namespace uri up, currently there isn't an
official mathml namespace)

then I have to change all my stylesheet to have 
 xmlns:mml="http://www.w3.org/Math/MathML/1.0" somewhere (OK)
and mml:  everywhere  (not so good).

I can't off hand see how I could write an XSL transformation to add the
namespace prefix either, as recognising source tree elements in the
stylesheet isn't so easy. (Unless I looked for each of the elements in
MathML individually.)

Perhaps the moral is: If you think that an XML application may sometimes
be used in a namespace, _always_ use it via a namespace. Something to
raise at the Math WG teleconference this afternoon....
