How to handle "xsd:anyAttributes" with jaxb

Question

Need help for how to handling "xsd:anyAttribute" with jaxb!
Here is part of my xml schema.
<xsd:attributeGroup name="DataAttributes">
<xsd:anyAttribute namespace="##local" processContents="lax"/>
</xsd:attributeGroup>
<xsd:element name="Data">
<xsd:complexType>
     <xsd:attributeGroup ref="DataAttributes"/>
</xsd:complexType>
</xsd:element>
<xsd:element name="MA_Verify">
<xsd:complexType>
     <xsd:sequence>
     <xsd:element ref="Data" minOccurs="0" maxOccurs="unbounded"/>
     </xsd:sequence>
     <xsd:attributeGroup ref="verifyAttributes"/>
</xsd:complexType>
</xsd:element>
I have an application which only knows the attribute names and values at runtime. (Thest attributes are string.) Therefore, I cannot define attribute names in the schema and have to use xsd:anyAttribute.
I was able to generate all jaxb code. However, the interfaces generated for Data and DataType are basically all empty. The impl classes are empty too, since no get or set methods exist for the attribute.
Some thoughts for handling this case, but do not know if it will work.
(1) write some derive classes on top of the generated jaxb classes.
(2) write customized method to handle the 'Data' element level and its attributes. Similar to parseMethod or printMethod for the javaType.
(if there is a way)
Can anyone give me suggestions, directions or an laternate way to handle the situation?
Your help will be greatly appreciated.

xsd:anyAttribute is not supported by JAXB.
