Answering my own question ...
Based on
http://weblogs.java.net/blog/kohsuke/archive/2006/03/why_does_jaxb_p.html
I replaced
<xsd:element name="r" type="main:CT_R"/>
with
<xsd:element name="r">
<xsd:annotation>
<xsd:appinfo>
<jaxb:class name="R"/>
</xsd:appinfo>
</xsd:annotation>
<xsd:complexType>
<!-- was name="CT_R" -->
<xsd:sequence>
<xsd:element minOccurs="0" ref="main:EG_RPr"/>
<xsd:group minOccurs="0" maxOccurs="unbounded"
ref="main:EG_RunInnerContent"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
Now the generated classes (and ObjectFactory) don't contain both
org.docx4j.jaxb.document.r and JAXBElement representations for r, and
marshalling works as well.
cheers
