Hello all! I think I came to a solution of what I was trying to.
What I wanted was to develop an XSL to append the content of one
XML document to another. I also wanted the XSL to be as general as
possible, so that I could use the XSL for any kind of XML document.

I don't know whether it is efficient or not. At least it does what
I was after. It might not be so efficient with large documents to
append.

Now, the input XML document to my XSL is of the form:

<append root="a_qname">
    <file>URI to file</file>
    <file>URI to file</file>
    ...
<append>

The value of the "root" attribute is the name of the root element
to be kept in the output, so any element with that name (which
should be the root element name of the documents to append) will
be ignored in the result.

Example:

input XML document:
===================
<append root="library">
    <file>file1.xml</file>
    <file>file2.xml</file>
<append>

Note: file2.xml could have also a root element <library>; this
      would be ignored.

file1.xml                      file2.xml
=========                      =========
<library>                      <book isbn="77">
   <book isbn="1">                <author>A77</author>
      <author>A1</author>         <title>T77</title>
      <title>T1</title>        </book>
   </book>
   <book isbn="2">
      <author>A2</author>
      <title>T2</title>
   </book>
</library>

RESULT:
=======
<library>
   <book isbn="1">
      <author>A1</author>
      <title>T1</title>
   </book>
   <book isbn="2">
      <author>A2</author>
      <title>T2</title>
   </book>
   <book isbn="77">
      <author>A77</author>
      <title>T77</title>
   </book>
</library>


My XSL:
