Q: How to select different style sheets at run time?

Hi,

I am wondering if anyone knows of a standard way to change the style sheet
applied to an XML document at run time. For example, I have a single XML
photo album document (see below) that contains both the thumbnail and
full-size versions of each photo. I have a default style sheet "album.xsl"
that displays a table with the thumbnails. What I would like is to somehow
make each thumbnail a link to the same XML document with a different style
sheet applied, say "photo.xsl". Microsoft has proprietary DOM extensions
that can do this; I was hoping there would be a more standard way. Seems
like there ought to be a way to specify "document + style sheet" in a URI...

Thanks, 
Todd

  <?xml-stylesheet type='text/xsl' href='album.xsl'?> 
  <ALBUM> 
    <PHOTO> 
      <CAPTION>Photo 1</CAPTION> 
      <THUMBNAIL SRC="t_photo1.jpg" /> 
      <FULL_SIZE SRC="photo1.jpg" /> 
    </PHOTO> 
    <PHOTO> 
      <CAPTION>Photo 2</CAPTION> 
      <THUMBNAIL SRC="t_photo2.jpg" /> 
      <FULL_SIZE SRC="photo2.jpg" /> 
    </PHOTO> 
  </ALBUM>
