My big XML book says it's not allowed. I made up a small example
(using XML authority, and XML Spy):

________________ DTD__________________
<?xml version='1.0' encoding='UTF-8' ?>

<!--Generated by XML Authority-->

<!ELEMENT e1 (#PCDATA)>
<!ATTLIST e1  a1 CDATA  #IMPLIED >
_______________________________________

I was hoping that defining a1 as CDATA (character data)
instead of PCDATA (parsed character data) would help
but XML Spy says that the following XML document:
___________________________________________
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE e1 SYSTEM "D:\tmp\e1.dtd">
<e1 a1="<![CDATA[jjj]]>"><![CDATA[jjj]]></e1>
___________________________________________
is not even well formed. Using CDATA within the body
of the elements (second CDATA in the example) is ok.
Generally markup is not allowed for attributes.
This might be another argument for rather using
elements than attributes.

So in summary I think at least some entities should
be supported by an Eiffel XML parser and the CDATA
as well for the elements.
