Extended-XSLT ?

I read a lot about Extended-XSLT, but I can't find any documentation about
it......
Where can I find more information about E-XSLT?

Ah...I overlooked it when reading the spec....maybe it's a good idea for me
to read the whole spec again ;-)

Thanks for the example.....it made things clear.

"E-XSLT" is a term that's kind of been coined along the
way during discussion on this list. It stands for:

"XSLT with tag libraries of Extension Elements"

The XSLT Extension Element feature is documented
in the spec at:

http://www.w3.org/TR/xslt#extension-element

This defines how a stylesheet/transform can 
identify "extension-element-prefixes" that
key the XSLT Processor into the fact that
certain XML namespaces represent libraries
of extension elements like:

  <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                 xmlns:quickquotes="urn-quickquotes"
                 version="1.0">
     :
  <quickquotes:get-quote symbols="AAPL GE HLTH"/>
     :

The implementation of the "get-quote"
extension element in the "mylib" library
gets a chance to do arbitrary processing and
then (perhaps) write some XML nodes as
its output into the result page.

So the result might be:

      :
    <quote>
      <ticker>AAPL</ticker>
      <price>105.62</price>
    </quote>
    <quote>
      <ticker>GE</ticker>
      <price>136.00</price>
    </quote>
    <quote>
      <ticker>HLTH</ticker>
      <price>72.88</price>
    </quote>
       :
