Tim,

What's happening is you're triggering the default templates that are 
provided by the XSLT processor that match element and text  nodes when 
you call <xsl:apply-templates/>. There are built in rules provided by 
the XSLT processor that match the different node types. The default rule 
for element nodes is to simply call <xsl:apply-templates/> again on its 
children nodes. The default rule for a text node is to print out the 
text to the output.

So when you call <xsl:apply-templates/> in your XSL, it's actually 
matching all the nodes, not just the <To> element, and it's firing the 
default template for everything but the <To> element, which fires the 
more specific template that matches the <To> element. This has the 
effect of printing out out all the text of each of the elements.

And actually it looks like it might not be matching the <To> element 
either, because it has a namespace in the source XML document that 
you're not specifying in your XSL. Your namespaces need to match between 
your XSL and your input XML document, otherwise the processor will not 
match it.
