While I am not completely familiar with all of Panorama's specific needs, I
am assuming it can deal with well constructed SGML. If this is the case,
then your Entity Declaration is where you are going wrong.

<!ENTITY accessuse PUBLIC "-//(..text snipped...)//TEXT
(URL of HTML document)//EN" NDATA HTML>

Where you have the string "URL of HTML document", you should have a name
unique in the server environment in which you are working for the document.
 For example:

<!ENTITY accessuse PUBLIC "-//(..text snipped...)//TEXT
(The Blah-blah-blah document)//EN" NDATA HTML>

And then following the ..//EN" and before the "NDATA HTML" You should have
the URL for the document to which you are providing a link:

<!ENTITY accessuse PUBLIC "-//(..text snipped...)//TEXT
(The Blah-blah-blah document)//EN" "URL://" NDATA HTML>

It is this latter piece of information that will supply the information
Panorama needs to find the specified file. (There are a couple of other
ways of doing it, but I would try to make this work before using more
complex, more robust approaches.

I hope this helps.
