Here's an example:

-- DTD --
...
<!element acl.index         - -   (chapter*)>
<!element chapter           - o   empty>

<!attlist chapter
    chapter     entity      #required
>
...
-- Document --
<!doctype acl.index public "-//Avionitek//DTD ACL Index//EN" [

<!entity com2.21 system "AirConditioning(2-21).sgml" subdoc> 
<!-- replace with 'public "..."' if you like -->
<!entity com2.49 system "APU(2-49).sgml" subdoc>
<!entity com2.52 system "Doors(2-52).sgml" subdoc>
...
]>
<acl.index>
<chapter chapter="com2.21" >
<chapter chapter="com2.49" >
<chapter chapter="com2.52" >
...
</acl.index>

-- Stylesheet --
...
(element acl.index (process-children))
(element (acl.index chapter) (subdoc))

(define (subdoc)
    (process-node-list
        (sgml-parse (entity-generated-system-id (attribute-string
"CHAPTER")))
    )
)
...

Enjoy!
