Exalt uses lxml, which in turn uses libxml2.

xmllint (which is the command-line interface to libxml2), gives the same result for your example document:

 /p/tmp $ cat test.xml
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE name [
    <!ELEMENT name (fname,lname)>
    <!ELEMENT fname (#PCDATA)>
    <!ELEMENT lname (CDATA)>
]>

<name>
    <fname>Vaibhav</fname>
    <lname>Bansal</lname>
</name>
 /p/tmp $ xmllint --valid test.xml
test.xml:11: element lname: validity error : Element lname content does not follow the DTD, expecting (CDATA), got (CDATA)
    <lname>Bansal</lname>
                         ^
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE name [
<!ELEMENT name (fname , lname)>
<!ELEMENT fname (#PCDATA)>
<!ELEMENT lname (CDATA)>
]>
<name>
    <fname>Vaibhav</fname>
    <lname>Bansal</lname>
</name>
 /p/tmp $

I'm by no means an expert on DTDs, but this Stack Overflow answer indicates that CDATA is not a valid content model for elements.
