You should only have your source listed on the replacement things, otherwise they will be active whenever any source from any of its usesource elements is active.

For example

<thing id="ExampleThing" replaces="OldThing">

     ...

     <usesource source="OldSource"/>
     <usesource source="NewSource"/>

</thing>

ExampleThing will replace OldThing whenever OldSource is active or NewSource is active.



If you remove the usesource element for OldSource, it will only replace OldThing when NewSource is active.

<thing id="ExampleThing" replaces="OldThing">

     ...

     <usesource source="NewSource"/>

</thing>

ExampleThing will only replace OldThing whenever NewSource is active.

I have just the new source, not the old one.
