Using a processing instruction to indicate customization URL

Hi,

 

I am new to DocBook and XSLT.  I am
using DocBook with DocBook XSL 1.69.1.

 

I want to use a processing instruction in
my DocBook XML to indicate the location of my customization.xsl file. I was
hoping it would look something like:

 

<?xml version="1.0"?>

<?MyInstruction CustomizationLayer=" customization.xsl" ?>

<book>   

   .

   .

   .

</book>

 

I would then write a template to capture
the value such as:

 

<xsl:template
match="processing-instruction(‘MyInstruction’)">

   “do something here”

</xsl:template> 

 

However, I am unable to capture “MyInstruction”
at all. It does work if I put the processing instruction in the “<chapter>”
element, but this would be inappropriate.

 

Can someone tell me the proper way to
handle this?
