Looks good with one minor comment. Go ahead and create the CSR once you make the requested update.

modules/javafx.base/src/main/java/javafx/beans/value/ObservableValue.java line 46:

Minor: either add `the` before `"Implementation Requirements"` here or remove `the` from the earlier line for
consistency.

Minor: as long as you are here, can you break this line between `An` and `invalidation`? In addition to wrapping a long
line, it will reduce the diffs, which seems good given that there will be an associated CSR.
