Upon reading the current work document, I encountered the following:
Unless other specified, if a DOM attribute that is a signed numeric
type is assigned a negative value, a NOT_SUPPORTED_ERR exception must
be raised.Is this correct? To my mind, a "signed type" should be
allowed to take a
negative value. If not, why have signed types? Does the document mean to
say that an *unsigned* type is assigned a negative value the exception
must be raised?
