[xml-dev] contradictory loader ordering in 3.5

I've got 3 modules which define their own DataLoaders, but which edit
xml files.  To get my loader before the XMLDataObject's loader, I'd
specify in my manifest:

Name: com/nuance/tools/voicexml/VoiceXMLDataLoader.class
OpenIDE-Module-Class: Loader
Install-Before: org.netbeans.modules.xml.core.XMLDataObject

This always caused a warning in 3.4, but it still worked.  Now, it
causes an exception, and I have to manually move my VXML data loader
above the XML one in the "Object Types" section of the Options menu. 

My running theory is that it's got something to do with the module's
dependencies:

OpenIDE-Module-Module-Dependencies:
  org.netbeans.modules.xml.tools/2 > 0.8,
  org.netbeans.modules.xml.tree/2 = XMLr35,
  org.netbeans.modules.xml.core/2 = XMLr35

Is the fact that I want my data loader loaded before the one in
xml.core a problem, seeing as though I'm dependent on xml.core?

 The exception is:
