Section 7.18.1 says:

   In order for a device to implement a feature that is dependent on any
   other features (i.e., the feature has one or more "if-feature" sub-
   statements), the device MUST also implement all the dependant
   features.

It should say:

   In order for a device to implement a feature that is dependent on any
   other features (i.e. the feature is a sub-statement of another 
   "if-feature" statement), the device MUST also implement all the 
   dependent features.

Notes:

The direction of the dependency is stated backwards.
Consider for example:

if-feature aaa;
statements ...;
if-feature bbb;

This should allow feature aaa to exist without feature bbb.
bbb should depend on aaa, but aaa should not depend on bbb

The current text is correct, according to Kent Watsen
