I am certain that the intention is that the answer be "no", and the first clause of Schema Component Constraint: Derivation Valid (Extension) is supposed to rule it out. However, given that a "prohibited" attribute produces no component in the component model, it looks like there is a bug in that clause that fails to account for that case. //Mary Dare Obasanjo writes: > > 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. > > [0] http://lists.w3.org/Archives/Public/xmlschema-dev/2002Jul/0213.html > > -- > PITHY WORDS OF WISDOM > Entropy isn't what it used to be. > > > This posting is provided "AS IS" with no warranties, and confers no > rights. -- -- Mary Holstege@mathling.com
