Not.

Why?

RFC4408 section 6.2 explains what happens in case of an empty
domain-spec ( "exp" "=" domain-spec ).

"  If <domain-spec> is empty, or there are any DNS processing errors
   (any RCODE other than 0), or if no records are returned, or if more
   than one record is returned, or if there are syntax errors in the
   explanation string, then proceed as if no exp modifier was given.
"

It is specifically mentioned, thus cannot be a syntax error.
