JAXB xjc class generation - recursive element/namespace collisions - jaxb

Question

I'm trying to generate classes for the ECMA-376 v5 schemas, but can't fix a collision of two elements via bindings customization, i.e. it will throw an [ERROR] Two declarations cause a collision in the ObjectFactory class error.
To try it yourself, just put the below ant build and the bindings file in a directory and call "ant" to setup and generate the classes.
If you uncomment the "Fixme" line in the ooxml.xjb, the generation will succeed, but looking at the src/org/openxmlformats/schemas/wordprocessingml/_2006/main/ObjectFactory.java you'll find the "Fixme" element is generated differently and probably doesn't make sense. So maybe use it just as a hint for your fix.
I guess the error is caused by the multiple "r" elements/references in ...:
wml.xsd->CT_RunTrackChange->EG_ContentRunContent->r
wml.xsd->CT_RunTrackChange->shared-math.xsd->EG_OMathMathElements->r
shared-math.xsd->EG_OMathElements->EG_OMathMathElements->r
shared-math.xsd->EG_OMathElements->wml.xsd->EG_PContentMath->EG_ContentRunContentBase->EG_RunLevelElts->EG_MathContent->shared-math.xsd->oMath->CT_OMath->EG_OMathElements... (see 3/4)
Although there are references on SO, that -XautoNameResolution would help, this seems to be futile in my case.
If nothing helps, I probably will search/replace the fixme tokens after generation, but I guess the correct binding instructions are not far away ...
In case you wonder why I use Moxy. This is a prototype for Apache POI and Moxy is suitable for android-conversion and license compatible - in any case I aim for a solution which preserves the XML infoset.
