  "A list used by datatype libraries to expand names.
The car of the list is a symbol which is the name of a function.
This function is applied to the cdr of the list.  The function must
return a list whose car is the default namespace and whose cdr is an
alist of (PREFIX . NAMESPACE) pairs, where PREFIX is a string and
NAMESPACE is a symbol.  This must be dynamically bound before calling
a datatype library.")
