Hi,
Well if you have no option to change this behaviour, IE it may
be possible to design this slightly odd behaviour out in the application
design you will have to look at complex options.
You will either need a custom action to change the component state.
Or maybe you could place your core application components in a hidden
feature that is always installed and give the user two visible features
in the UI that are mutualy exclusive.
Feature1 - all core components - Hidden in the UI.
Feature2 - component A - just has the abc.txt component
Feature3 - component B - has xyz.txt component and other optional
features.
I'm not sure how painful making the feature UI do mutex features will be
though as we don't use the built in UI.

Yes.. This is exactly the problem I am facing. I have a requirement that
Feature 2 should be a child of Feature 1. Feature 1 is always installed.
Feature 2 is an optional component.
