Re: [SOAP] Custom SOAP Types of Custom SOAP types?

I was doing some reading and I came across someone talking about building a usertype that extends another usertype. So I could have a base type of vehicle, and derived types of car and truck. Letting me re-use the definition of vehicle that I've already created. And then I should be able to pass back an array of vehicles weather they are cars or trucks, and have my client be able to handle everything seamlessly. The information I came across was talking about the restricted tag and the base attribute. I was wondering if anyone new any more about this, or if there are some conventions in PEAR::SOAP to deal with this?
