Yes, and especially in this case this kind of reply is, I believe, the
most necessary for the group of very basic, core questions about XSLT.

This is why we have programming environments. I know at least two of
them (XSelerator and Visual Studio 2008/2005), which allow the XSLT
programmer to define skeletal code (a "snippet") to be displayed on
initial creation of an XSLT file.

I am using one of these programming environments on a daily basis.
Whenever I am creating a new XSLT 2.0 file with it, it automatically
displays the following starting code:

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xmlns:f="http://fxsl.sf.net/"
 exclude-result-prefixes="f xs"
 >

 <xsl:template match="/">

 </xsl:template>
</xsl:stylesheet>

and I do not have any problems with the prefixes ( either defining or
pruning them) I use most frequently.

I have another new-template that automatically creates the identity
rule for me, ..., and the possibilities for personalization are
virtually unlimited.


Certainly, such features are a must for any modern XSLT programming environment.

On the other hand, even using them does not mean the programmer should
not understand the auto-generated code (such as the
"exclude-result-prefixes" attribute) and this leads us at the point
where we started: training.

Let me congratulate Dr. Kay on the 4th edition of his "XSLT
Programmer's Reference" book. Although I have had for years his two
books on XSLT 2.0 and XPath 2.0, I am now ordering this new, 4th
edition.
