You can't dynamically generate the string that is used in an ENTITY
definition.  However, you *can* do this if, instead of using an
ENTITY, you store the string as a global variable, and then refer to
it as such.

You can store the CONFIG element from (let's say) message.xml, in a
variable using the document() function to access the root node of the
document, and an XPath to access the CONFIG element from there:

<xsl:variable name="config"
              select="document('message.xml')/MESSAGE/CONFIG" />

Now, the base URL for the files can be generated by concatenating the
FILES/SERVER and FILES/PATH together, with a '/' separator and
prefixed with 'http://':

  concat('http://', $config/FILES/SERVER, '/', $config/FILES/PATH)

If you're only accessing this information once, then you could just
use that, but otherwise it's worth putting it in a variable:

<xsl:variable name="file-base-url"
              select="concat('http://', $config/FILES/SERVER, '/',
                             $config/FILES/PATH)" />

Then, you can include this variable within your XSLT, either using:

  <xsl:value-of select="$file-base-url" />

or, if you're within an attribute, using an attribute value template:

  {$file-base-url}

In your case, for example, you can do:

<xsl:template match="/">
  ...perform some code...
  <img src="{$file-base-url}/images/name.gif" />
  <xsl:apply-templates select="//Names/Name" >
    <xsl:sort select="FN" />
  </xsl:apply-templates>
</xsl:template>

I hope that this helps,
