assuming your grammar is BNF so valid sentences would be e.g.:-
(lambda fred xyz)
(lambda a234 adf)
etc
then such expressions would not be valid xml, so you can't really write a
DTD for them.
an XML equivalent of what you appear to be attempting might be something
like:-
<lambda>
<name>fred</name>
<body>xyz</body>
</lambda>
for which the DTD would look like:-
<!ELEMENT lambda (name , body )>
<!ELEMENT name (#PCDATA )>
<!ELEMENT body (#PCDATA )>
