Please look at the saxon extension function saxon:doctype.
http://saxon.sourceforge.net/saxon6.5.5/extensions.html#saxon:doctype
which provides the mechanism to create the entities. In your
case you have to re-generate the entities in XML file.
I suspect that he wants entity references to be copied, rather than entity
declarations. The saxon:doctype extension allows you to construct a DTD
(internal subset) containing entity declarations, and you can construct
references to those entities using character maps or
disable-output-escaping. But to get access to entity declarations and entity
references in the source XML, you need to stop the XML parser expanding
them, which you can do using Andrew Welch's LexEv.

I am sorry I forgot to mention one piece of information

input files were originally SGML and were then converted to well

attribute values, not using & ; notation.
So when I do the <xsl:copy> the entities are not copied over.
parsed entities (referenced by &) are expanded by the XML parser
before XSLT even sees the input. So XSLT can not copy them
as it never
sees them.
But you can not reference a jpg file that way.
An NDATA entity is referenced as attribute value typically
something
like
<!ENTITY spoon.jpg SYSTEM "spoon.jpg" NDATA jpg>
...
<image ref="spoon.jpg"/>
...
if you access the entity this way, then the attribute value is
available to xslt and you can look up the SYSTEM URI using
unparsed-entity-uri().
But you showed a parsed entity declaration
<!ENTITY spoon.jpg SYSTEM "spoon.jpg" >
which would be acceessed by
& s p o o n . j p g ;
such a reference would be expanded by the xml parser before
xslt sees
the data (and generate a fatal error if it is a jpeg file
rather than
xml)
As you haven't shown how you are referencing the entities in the
source file I can't really guess what to suggest.
