Adding entity declarations to DOCTYPE in xml output

Hello collective wisdom -

I would like to have several entity declarations in my output XML.  Here's
what I currently have in my XSL:

<xsl:output
   method="xml"
   indent="yes"
   encoding="utf-8"
   exclude-result-prefixes="ns"
   omit-xml-declaration="yes"
   doctype-system="../ead_dtd/ead.dtd"
   doctype-public="+//ISBN 1-931666-00-8//DTD ead.dtd (Encoded Archival
Description (EAD) Version 2002)//EN"/>


The output XML looks like this:

<!DOCTYPE ead PUBLIC "+//ISBN 1-931666-00-8//DTD ead.dtd (Encoded Archival
Description (EAD) Version 2002)//EN" "../ead_dtd/ead.dtd">


I would like it to look like this:

<!DOCTYPE ead PUBLIC "+//ISBN 1-931666-00-8//DTD ead.dtd (Encoded Archival
Description (EAD) Version 2002)//EN" "../ead_dtd/ead.dtd" [
<!ENTITY sua_name SYSTEM "sua_name.txt">
<!ENTITY sua_address SYSTEM "sua_address.txt">
<!ENTITY subjindex SYSTEM "sua_index.txt">
<!ENTITY summitref SYSTEM "summit_ref.txt">
]>


Is this doable with XSL 1.1?

Thanks --

Michele
