@@ -41,7 +41,6 @@ A boundary variable inherits the values of some attributes from its parent coord
 If a coordinate variable has any of the attributes marked "BI" (for "inherit") in the "Use" column of <<attribute-appendix>>, they are assumed to apply to its bounds variable as well.
 It is recommended that BI attributes not be included on a boundary variable.
 If a BI attribute is included, it must also be present in the parent variable, and it must exactly match the parent attribute's data type and value.
-A boundary variable can only have inheritable attributes if they are also present on its parent coordinate variable.
 A bounds variable may have any of the attributes marked "BO" for ("own") in the "Use" column of <<attribute-appendix>>.
 These attributes take precedence over any corresponding attributes of the parent variable.
 In these cases, the parent variable's attribute does not apply to the bounds variable, regardless of whether the latter has its own attribute.
