[xsl] What is the simplest method for using xsl:sort without losing attribute names and values?

["Mark Wilson" <mark@xxxxxxxxxxxx>]

I am very inexperienced, using XSLT 2.0 with Saxon B9.0.0.6 in Oxygen on 
Windows Vista. I have Michael Kay's book, but do not know enough to find the 
answer to my question on my own.

I want to do a simple sort without losing either elements or attributes. The 
xls style sheet I have written works, but there must be a more
succinct method. One element <Cat> has four attributes (two optional), the 
other <Person> has one optional attribute. When the templates for <Cat> and 
<Person> are not present in my style sheet, I lose the attributes but not 
the elements themselves.

Is the answer somewhere in apply-templates? Without the two templates, when 
I tried <xsl:apply-templates select="@* | node()"/>,  I got the value of the 
attributes as a list within the start tags but without their names. Did I 
miss something?

Thanks for any help,
Mark
