Documentation of dependency properties is not consistent and confusing.

### Type of issue

Missing information

### Description

[Enter feedback here]
Many dependency properties include "This is a dependency property" in their description. However, not all dependency properties include it. This can be confusing, as you might think you can't use a property like Foreground as the target of a binding. But it IS a dependency property. It just isn't documented as consistently as the others. This feels like something you could make a generator do for you.
