The design of xml entities is that the physical distribution of the
document overfiles should not influence the logical document represented
by the xml markup. Xpath (and so xslt) strictly adheres to this
viewpoint and so the entities are fully expanded (leaving no record) as
the input tree is constructed.
You have two choices, edit your included documents so the top level
element has an id or edit your including document so that the reference
is marked, eg wrap each entity reference in an element.
<fileref id="myfile">&myfile;</fileref>
Which could be done using any regexp capable editor or perl or sed or
something like that.

Which isn't strictly true. There is record left of the extrenal entity
as the base uri of the node, which is used for resolving relative uri in
the document() function, but not otherwise available in xslt/xpath 1.
However it _is_ available in XPath2 so if you use saxon7 i think
(untested) you should be able to use base-uri() to access this.
In XSLT1 you can not access the uri (ie file name) but you can detect
that you are in an external entity as document('') pulls in a different
file in this case (assuming that the entity is well formed if read as a
document, which need not be the case.
In the following example there are three y elements and xslt reports
them as being in three different documents, as the generate-id are
different:
en1.xml:
<!DOCTYPE x [
<!ENTITY a SYSTEM "ena.xml">
<!ENTITY b SYSTEM "enb.xml">
]>
<x>
&a;
&b;
<y/>
</x>
ena.xml:
<y/>
enb.xml:
<y/>
en1.xsl:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:template match="*">
:<xsl:for-each select="ancestor::*">:</xsl:for-each>
<xsl:value-of select="name()"/>
<xsl:text> - </xsl:text>
<xsl:value-of select="generate-id(document('',.))"/>
<xsl:apply-templates/>
</xsl:template>
</xsl:stylesheet>
$ saxon en1.xml en1.xsl
<?xml version="1.0" encoding="utf-8"?>
:x - d1
::y - d2
::y - d3
::y - d1
