BTW why has it been removed (from the draft) ?

We decided to deprecate disable-output-escaping altogether in XSLT 2.0
because of the architectural problems it causes (it requires close-coupling
between the transformation engine and the serializer, which prevents
transformations being pipelined). And it didn't make sense to extend the
scope of a feature and deprecate it at the same time.

For writing ASP pages, character maps are a much better solution.
