First, from what I've seen, I fear your DocBook5 document is not valid. 
DocBook5 does not have any bookinfo elements anymore. It is replaced with 
info. As a rule of thumb, always validate your document before applying 
any transformations on it. :)

Second, as you have a DocBook5 document, you have to use the respective 
namespace in your stylesheets too. Declare it in your root element, for 

 <xsl:stylesheet version="1.0"

After this modification, you have to use the declared prefix on all your 
DocBook5 elements:

 <xsl:apply-templates select="d:info/d:title"/>

However, a title can occur not only inside a d:info element, it can occur 
directly after d:book too. Probably it is better to extend the above 
expression like this (if your current context is d:book):

 <xsl:apply-templates select="(d:info/d:title|d:title)[1]"/>

This selects only one of the possible titles, either in d:info or in 
d:book. If you need only the string content of a title regardless of the 
elements inside, replace xsl:apply-templates with xsl:value-of.

This is just a general explanation, maybe you have to play with the 
customization a bit and use other modes. See also Bob's book for more 
information at http://www.sagehill.net/docbookxsl/index.html

I'm not sure what you mean by "changing the reference of the document

Probably the same issue as above.

Hope that helps,
