not understanding ConTeXt-XML

not understanding ConTeXt-XML

I guess I am a bit stupid, but I do not understand how to process xml  
in ConTeXt.
I started working through the contextXML-example.pdf from the Pragma  
site.
I tried to follow the example on page 8 which reads:
% here go style definitions
% and XML to TEX mappings
\starttext
\processXMLfilegrouped {filename.xml}
\stoptext

In TeXShop (working in the latest context-beta) I have the tex-input:

\def\Filenumber#1{[#1]}

<xsl:template match="dvd">
	<xsl:apply-templates/>
</xsl:template>

<xsl:template match="dvd/filenumber">
	<xsl:text>\Filenumber{</xsl:text>
	<xsl:text>{\bf </xsl:text>
	<xsl:apply-templates/>
	<xsl:text>}</xsl:text>
	<xsl:text>}</xsl:text>
</xsl:template>

\starttext
\processXMLfilegrouped {xml-input.xml}
\stoptext

and in file name.xml:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<dvd>
	<filenumber>D134</filenumber>
</dvd>

I get the obviously wrong result:

<xsl:template match="dvd"> <xsl:apply-templates/> </xsl:template>
<xsl:template match="dvd/filenumber"> <xsl:text>[</xsl:text>  
<xsl:text></xsl:text>
<xsl:apply-templates/> <xsl:text></xsl:text> <xsl:text>]</xsl:text> </ 
xsl:template>
D134

My main problem seems to be the proper incantations and in the right  
order.
What is the relation between the <xsl:template>-definitions and the  
xml-processing, because these data show up in the result?
What is in this respect the function of macros like  
\defineXMLenvironment, etc? From the example document I cannot infer  
the relation between these and the <xsl:template>-definitions.
Just some pointers in the right direction may set me on the right  
track. Thanks in advance.

For MKII you need the \defineXMLenvironment etc. commands.

For MKIV you should first read Thomas MyWay:
