Chad, I think you're confusing RoleDescriptor with the EndpointType's 
(which BTW, for everyone else, themselves actually aren't xs:anyType, 
but have wildcard <any> elements and <anyAttribute> and we implement in 
a similar manner as the xs:anyType's).

In the metadata schema, RoleDescriptorType is just a standard global, 
named type.  But it's abstract, and therefore so are the corresponding 
opensaml2 classes (impl, marshaller, unmarshaller), so that's why 
there's no builder - you can't build an element with that default type 
or with an explicit type declaration of xsi:type="RoleDescriptorType".

This is what you want to consult.  It may be a little out of date.

More specifically:

You need to extend the RoleDescriptor interface with a new interface 
that represents the things in your extension content model for the 
OnlineCADescriptor.    Be sure to override the TYPE_LOCAL_NAME and 
TYPE_NAME constants.

Then supply a new non-abstract impl, which implements the new interface 
and extends RoleDescriptorImpl.  Also extend RoleDescriptorMarshaller 
and -Unmarshaller appropriately.

Then supply a builder that builds the object.

Take a look at our code for one of the concrete SAML 2 role descriptors 
for an example, e.g. AttributeAuthorityDescriptor.

Also, you need to implement providers for whatever other new 
types/elements you may have defined as content of the role descriptor, 
such as egmd:OnlineCAService (looks like maybe a new type by extension 
of EndpointType?).

Finally register those new providers in a new config file and load the 
new providers into the runtime Configuration, either by extending 
DefaultBootstrap, or by using XMLConfigurator directly.
