I am using the Force.com Migration Tool...  I have a scenario where picklist values are to be removed.  My initial reaction was to dentote something like the following in my destructiveChanges.xml:

<types>

    <members>TheObject.ThePicklist</members>

    <name>CustomField</name>

</types>

That, of course, will remove the entire picklist...and I can deploy the new picklist...

The biggest problem is that if the picklist is referred to anywhere, failure arises for the destructive change...  What I really need is the capability to solely denote the picklist values I want to remove.  I tried a number of different naming conventions - none of which worked (for example, TheObject.ThePickllist.ThePicklistValue)...

Is there any way to put a trigger on a ContentDocument?  I would like to have an action fire after one is deleted from the system, but it looks like I can only create a trigger on ContentVersion.

Any thoughts?
