Which represents the text string "&dt=..." ... it does not represent 
an entity reference.

Which processor are you using?

An example below uses Saxon with its XML processor.

So you are talking about a text node ... but <![CDATA[&amp;dt=...]]> 
represents the string "&amp;dt=...", not "&dt=..."

>How can I handle such examples of &amp;dt= ?

I'm not sure what you mean by "handle" ... that string represents 
"&dt=" and enclosing it in a CDATA section does not give you the same string.

I hope this and the code below helps clarify what you are expressing 
with your syntax.
