About 1.5 years ago one of our developers asked whether an attribute [or
element] removed by restriction could be added back in an extension.
Looking back at the message[0] there was no conclusive answer from the
working group and most implementations allowed attributes and elements
removed by restriction to be added back by extensions. 

I'd appreciate it if a definitive answer could be provided.
