within it.
The @qq{accepts} list of a context can be changed with the
-@code{\accepts} and @code{\denies} commands. @code{\accepts} adds a
+@code{\accepts} or @code{\denies} commands. @code{\accepts} adds a
context to the @qq{accepts} list and @code{\denies} removes a context
-from the list. For example, it would not normally be desirable for
-chord names to be nested within a @code{Staff} context, so the
-@code{ChordNames} context is not included by default in the @qq{accepts}
-list of the @code{Staff} context, but if this were to be required it can
-be done:
+from the list.
+
+For example, a square-braced staff group is not usually found within a
+curved-braced staff with connecting staff bars, and a @code{GrandStaff}
+does not accept a @code{StaffGroup} inside it by default.
