note parameters to not-found-proc, use hyphens rather than underscores
for that parameter name.
In primitive-property-set!, VAL is the value parameter not CODE.

@deffn {Scheme Procedure} primitive-make-property not_found_proc
@deffn {Scheme Procedure} primitive-make-property not-found-proc
@deffnx {C Function} scm_primitive_make_property (not_found_proc)
Create a @dfn{property token} that can be used with
@code{primitive-property-ref} and @code{primitive-property-set!}.
See @code{primitive-property-ref} for the significance of
@var{not_found_proc}.
@var{not-found-proc}.
@end deffn
@deffn {Scheme Procedure} primitive-property-ref prop obj
@deffnx {C Function} scm_primitive_property_ref (prop, obj)
Return the property @var{prop} of @var{obj}. When no value
has yet been associated with @var{prop} and @var{obj}, call
@var{not-found-proc} instead (see @code{primitive-make-property})
and use its return value. That value is also associated with
@var{obj} via @code{primitive-property-set!}. When
@var{not-found-proc} is @code{#f}, use @code{#f} as the
default value of @var{prop}.
Return the property @var{prop} of @var{obj}.
When no value has yet been associated with @var{prop} and @var{obj},
the @var{not-found-proc} from @var{prop} is used. A call
@code{(@var{not-found-proc} @var{prop} @var{obj})} is made and the
result set as the property value. If @var{not-found-proc} is
@code{#f} then @code{#f} is the property value.
@end deffn
@deffn {Scheme Procedure} primitive-property-set! prop obj val
@deffnx {C Function} scm_primitive_property_set_x (prop, obj, val)
Associate @var{code} with @var{prop} and @var{obj}.
Set the property @var{prop} of @var{obj} to @var{val}.
