public class StartTagBuffer extends ProxyReceiver implements NamespaceResolver
StartTagBuffer also implements namespace fixup (the process of creating namespace nodes|bindings on behalf of constructed element and attribute nodes). Although this would be done anyway, further down the pipeline, it has to be done early in the case of a validating pipeline, because the namespace bindings must be created before any namespace-sensitive attribute content is validated.
The StartTagBuffer also allows error conditions to be buffered. This is because the XSIAttributeHandler validates attributes such as xsi:type and xsi:nil before attempting to match its parent element against a particle of its containing type. It is possible that the parent element will match a wildcard particle with processContents="skip", in which case an invalid xsi:type or xsi:nil attribute is not an error.
