The important thing with XSLT is to know the XML structure of the input.

For the document-styling XSLTs, this is described here:

http://cocoondev.org/daisydocs-2_1/374-cd/g1/26-cd.html

As you can see, the root element is <document>, and below that is
<context>.

So the above XPath expression to get the user should be:

<xsl:variable name="user" select="document/context/user"/>

The other ones with reference $user should then automatically work.

BTW, the <page> root tag is what is used for the XML which is provided
to the layout.xsl, whose structure is described here:
