Web resource dependencies
Web resource dependencies were added with the Dynamics 365 for Customer Engagement apps version 9.0.
The dependency is only established after it is configured and the web resource is published. Dependencies for unpublished web resources will not take effect until the web resource is published.
Before this feature you would need to manually add the attribute to the form and then configure the control to be hidden. Now you can establish this dependency more directly and eliminate the possibility that someone will remove the hidden field from the form.
