How to automatically add xsd:attribute to xsd:complexType in Apache XMLBeans?

Question

We're running into some trouble with supplied XSDs of the following kind:

<xsd:complexType name="foo">
    ...
    <xsd:attribute name="version" fixed="1" />
</xsd:complexType>

The XML-Result is then expected look something like this:

<foo version="1">...</foo>

Since this is not how fixed attribute values are actually supposed to work XMLBeans will not generate such a result for us by default. We have hundreds of XSDs like this with varying versions and want to avoid adding them all by hand.

Does anyone know of a way to programmatically determine the values of fixed attributes of a given XMLObject so we can add them generically?

As described in the documentation provided by Petru Gardea's comment above you can access information about an XMLObjects schema, its attributes and their default values by using the SchemaTypeSystem.
