Re: Part 1, http://www.w3.org/TR/2009/WD-xmlschema11-1-20090130/ (1) Schema processors are now explicitly recommended to provide a user option to control whether the processor attempts to dereference schema locations indicated in schemaLocation attributes in the instance document being validated. See http://www.w3.org/TR/2009/WD-xmlschema11-1-20090130/#schema-loc. We are concerned whether the average user can be expected to make a reasonable decision whether the user agent should deference a schema location? After all, this decision may result in an invalidation of the current document. We are particularly concerned that this is an even greater burden for the user with a disability. Considerations on how to represent this question to the user are covered by UAAG, http://www.w3.org/wai/ua.
