I found this sentence as part of annex D of XML Schema Part 1, which should
back Merlin's opinion on the question wheter XML Schema changes the XML
infoset input:

  "This specification does not require any destructive alterations
   to the input information set: all the information set contributions
   specified herein are additive."

Considering this statement, I agree with Merlin: Xerces operates in error,
if it provides the "normalized value" instead of the "initial value" for
simple types in its DOM API.
