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.

PF thanks Joseph Scheuhammer <clown@utoronto.ca> and Gottfried
