XML-friendly hexadecimal references in Markup->Insert Entity?

Hello,

Has anyone come up with a way to have the Insert Entity menu under Markup 
insert the XML compliant hexadecimals (&#x[blah];) instead of character 
entities? I am pointing to a DTD (EAD) that does include xml entity sets 
(although the .pen file extension looks odd to me now).
e.g.
<snip>
<!ENTITY % isolat1 PUBLIC
   "ISO 8879-1986//ENTITIES Added Latin 1//EN"
   "..\char_ent\isolat1.pen"                                        >
</snip>

I see in my compiled .ced version of the DTD that it does list the ones 
pointed to by the .pen files:
<snip>
("lsquo" text "&#x2018;" nil) ("rsquo" text "&#x2019;" nil) ("ldquo" text 
"&#x201C;" nil) ("rdquo" text "&#x201D;" nil) ("nbsp" text " " nil) ("shy" 
text "­" nil) ("emsp" text "&#x2003;" nil)
</snip>


Thanks for any help or ideas.
Leslie
